Question

(b)Simplify:
(x²+x-6)=(x - 2)​

Answer 1

(x²+x-6)=(x - 2)

or, x2+3x-2x-6 =x-2

or, x(x+3)-2(x+3) =x-2

or, (x+3)(x-2) = x-2

or, x+3 =1

or, x=-2

Answer 2

Answer:

$\boxed{\bf x=-2,+2}$

Step-by-step explanation:

$x^{2} +x-6=x-2 \\ \\ x^{2} +x-6-x+2=0\\\\x^{2} -4=0\\\\x^{2} =4\\\\ x=\sqrt{4} \\\\ x=\pm2 \\\\ \boxed{x=-2,+2}$
