Question

Find the product of the roots of the equation (x + 1)(x - 2) + (x - 2) = 0​

Answer 1

Answer:

-2,2

Step-by-step explanation:

(x+1)(x-2)+(x-2)=0

$x^{2}$-$2x+x-2$ + x - 2 =0

$x^{2} -2x + 2X - 4 = 0$ ......................taking common.

$x ( x - 2 ) + 2 (x - 2 ) = 0$

$( x + 2 ) ( x - 2 ) = 0$

x + 2 = 0        OR       x - 2 = 0

x = -2      or     x = +2
