Summary

Summary of Quadratic Equations

A quadratic equation is of the form ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0.
A real number α is a root of the equation if aα² + bα + c = 0.
The roots can be found by factorizing the equation into linear factors.
Quadratic Formula: The roots are given by x = (-b ± √(b² - 4ac)) / (2a).
Nature of roots based on the discriminant D = b² - 4ac:
- Two distinct real roots if D > 0.
- Two equal roots if D = 0.
- No real roots if D < 0.

Detailed Notes

Quadratic Equations

Introduction

A quadratic equation in the variable x is of the form ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0.

Key Points

A real number α is a root of the quadratic equation ax² + bx + c = 0 if aα² + bα + c = 0.
The zeroes of the quadratic polynomial ax² + bx + c and the roots of the quadratic equation are the same.
If we can factorise ax² + bx + c into a product of two linear factors, the roots can be found by equating each factor to zero.
Quadratic formula: The roots of a quadratic equation ax² + bx + c = 0 are given by x = -b ± √(b² - 4ac) / (2a), provided b² - 4ac is defined.
Nature of roots based on the discriminant D = b² - 4ac:
- Two distinct real roots if D > 0
- Two equal roots if D = 0
- No real roots if D < 0

Examples

Example of a quadratic equation: 2x² + x - 300 = 0.
Example of finding roots by factorisation: 6x² - x - 2 = 0 can be factored to find roots.

Applications

Quadratic equations arise in various real-life situations, such as calculating areas, dimensions, and solving problems involving products and sums.

Exercises

Find the nature of the roots of the following quadratic equations:
- (i) 2x² - 3x + 5 = 0
- (ii) 2x² - 6x + 3 = 0
Determine the values of k for quadratic equations to have two equal roots:
- (i) 2x² + kx + 3 = 0
- (ii) kx(x-2) + 6 = 0
Solve real-life problems involving quadratic equations, such as designing a rectangular park or finding ages based on given conditions.

Exam Tips & Common Mistakes

Common Mistakes and Exam Tips for Quadratic Equations

Common Pitfalls

Misidentifying Quadratic Equations: Ensure the equation is in the standard form ax² + bx + c = 0. Some equations may appear quadratic but are not.
Ignoring the Discriminant: Always check the discriminant (b² - 4ac) to determine the nature of the roots. Misinterpretation can lead to incorrect conclusions about the existence of real roots.
Negative Roots: When solving for dimensions (like length or breadth), remember that negative values are not valid in real-world contexts.
Factorization Errors: Be cautious while factorizing quadratic equations. Incorrect factorization can lead to wrong roots.

Exam Tips

Use the Quadratic Formula: When in doubt, apply the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a) to find roots accurately.
Check Your Work: After finding roots, substitute them back into the original equation to verify correctness.
Understand the Nature of Roots: Familiarize yourself with the conditions for the nature of roots based on the discriminant:
- Two distinct real roots if b² - 4ac > 0
- Two equal roots if b² - 4ac = 0
- No real roots if b² - 4ac < 0
Practice Factorization: Regularly practice factorization techniques to improve speed and accuracy in solving quadratic equations.

6.5 m

5 m

7 m

8 m

Correct Answer: A

Solution:

The radius

r

of the circle inscribed in a right triangle is given by

r = \frac{a + b - c}{2}

, where

a

and

b

are the legs and

c

is the hypotenuse. Here,

a = x + 7

b = x

, and

c = 13

. Solving for

x

from the previous problem,

x = 5

. Thus,

a = 12

and

b = 5

r = \frac{12 + 5 - 13}{2} = \frac{4}{2} = 2

However, since the circle is circumscribed, the radius is half of the hypotenuse:

\frac{13}{2} = 6.5

s = r\sqrt{2}

s = 2r

s = \frac{r}{\sqrt{2}}

s = r

Correct Answer: A

Solution:

Simplifying,

2x^2 + 14x - 120 = 0

Divide by 2:

x^2 + 7x - 60 = 0

Using the quadratic formula,

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

, where

a = 1, b = 7, c = -60
