Question

(2x2+2x-6) (x+1)-(x2-x+3)(x-4)​

Answer 1

Step-by-step explanation:

(2*2+2x-6) (x+1)-(2x-x+3)(x-4)

(4+2x-6)(x+1)(-2x+x-3)(x-4)

x+1(4+2x-6) x-4(-2x+x-3)

4x+1+3x+2x-6x-6-3x+8x+2x-4x-3x+12

write same terms together:

4x+3x+2x+8x+2x-6x-3x-4x-3x+1+12-6

19x-16x+13-6

= 3x+7

(2*2+2x-6)(x+1)-(2x-x+3)(x-4)=(3x+7)
