Factor the polynomial completely. If the polynomial cannot be factored, write prime.
15x2 + 16x + 4
(3x - 2)(5x - 2)
(3x + 2)(5x + 2)
(15x + 2)(x + 2)
prime

= 15x2 + 16x + 4
= 15x2 + 10x + 6x + 4
= 5x(3x + 2) + 2(3x + 2)
= (5x + 2)(3x + 2 )
This is the solution!!

15x2+16x+4=0
sol:
15x2+10x+6x+4=0
5x(3x+2)+2(3x+2)=0
so (5x+2)=0 or (3x+2)=0
the answer is (5x+2)(3x+2)

(3x + 2) (5x + 2) is the answer.

(3x+2)(5x+2)
The second one you put down was right.
