Solved Example of Quadratic Equations

Shared here is an example from RD Sharma Class 10 Solutions from Chapter 8, of Ex 8.7, along with the solution:

Find two consecutive numbers whose squares have the sum 85. (from CBSE Question paper of 2000).

Ans:

Let first number = x

Then second number = x + 1

According to the condition

x² + (x + 1)² = 85

⇒ x² + x² + 2x + 1 = 85

⇒ 2x² + 2x + 1 – 85 = 0

⇒ 2x² + 2x – 84 = 0

⇒ x² + x – 42 = 0

⇒ x² + 7x – 6x – 42 = 0

⇒ x (x + 7) – 6 (x + 7) = 0

⇒ (x + 7) (x – 6) = 0

Either x + 7 = 0, then x = -7 or x – 6 = 0, then x = 6

(i) If x = -7, then the first number = -7 and second number = -7 + 1 = -6

(ii) If x = 6, then the first number = 6 and second number = 6 + 1 = 7

Hence numbers are -7, -6 or 6, 7.
