Question

Find the roots of the following quadric equations by factorization

Answer 1

- Answer is in the above attachment

Answer 2

GIVEN :

Quadratic Equations:

1) x² - 5x + 2x - 10 = 0

=> x² - 3x - 10 = 0

Split the middle term.

=> x² - 5x + 2x - 10 = 0

=> x(x - 5) + 2(x - 10) = 0

=> x - 5 = 0 ; x + 2 = 0

=> x = 5 and x = -2

2) 2x² + x - 6 = 0

Split the middle term.

=> 2x² + 4x - 3x - 6 = 0

=> 2x(x + 2) - 3(x + 2) = 0

=> 2x - 3 = 0 ; x + 2 = 0

=> 2x = 3 ; x = -2

=> x = 3/2 and x = -2
