check my work
1.a
2.c
3.b
4.c
5.d

I can confirm it is

C
A
B
D
A

Full answers are C A B D A

FULL ANSWER ARE C, A, B, D, A

In this forum we type powers using the ^ to show exponents

e.g 4x^2 , not 4x2

anyway
1.
4x^2 + 12x + 5 = (2x+1)(2x+5)

2.
2x^2 + x - 3 = (x-1)(2x+3)

3. ok

4.
16x^2 - 16x - 12
= 4(4x^2 - 4x -3)
= 4(2x+1)(2x - 3) which is D)

5.
= 3(x^2 + 7x - 8)
= 3(x+8)(x-1) which is A)

looks like some serious review is needed

They are 100%%% CABDA

can confirm..

1) C or (2x+1)(2x+5)
2) A or (2x+3)(x-1)
3) B or 2x-5
4) D or 4(2x-3)(2x+1)
5) A or 3(x+8)(x-1)

c,a,b,d,a
