1) q: a: factor x2 + 8x + 16 a) (x + 4)2 b) (x - 4)2 c) (x + 8)(x + 2) d) (x + 2)(x - 8)

(x+4)^2  Choice A

Step-by-step explanation:

x^2 + 8x + 16

what 2 numbers multiply together to give you 16 and add together to give you 8

1*16 = 16   1+16 = 17  no

2*8 = 16   2+8 = 10  no

4*4 = 16  4+4 = 8  yes

(x+4) (x+4)

(x+4)^2

-4(2+3+5-4)=-24

Step-by-step explanation:

Put together the common factor "-4" and x by numbers inside
