Question

Find the roots of the following quadratic equations by factorization : 1] x^2-3x-10=0​

Answer 1

Step-by-step explanation:

(i) x2 – 3x – 10

= x2 - 5x + 2x - 10

= x(x - 5) + 2(x - 5)

= (x - 5)(x + 2)

Roots of this equation are the values for which (x - 5)(x + 2) = 0

∴ x - 5 = 0 or x + 2 = 0

⇒ x = 5 or x = -2
