<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)

</span><span>zero-product property 
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
  x = -5/4
  x = -1.25

x - 5 =0
x = 5

answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25

Reorder 2 cos (2y) and sin (2y)

= sin (2y)(2 cos(2y))

Remove parenthesis

= sin (2y) * 2 cos (2y)

Reorder sin (2y) and 2

= 2 * sin (2y) cos (2y)

Apply the sine double-angle identity

= sin (2(2y))

Now multiply 2 by 2

<u>= sin (4y) </u>
