14. 36x^2 - 16
4(9x^2 - 4) =
4(3x + 2)(3x - 2) <==
15. 3x^2 + 10x - 8
(3x - 2)(x + 4) <==
16. 5x^2 - 16x + 15 = 4x - 5
5x^2 - 16x - 4x + 15 + 5 = 0
5x^2 - 20x + 20 = 0
5(x^2 - 4x + 4)
5(x - 2)(x - 2)
x - 2 = 0....x = 2

Answer: 1/10
Step-by-step explanation:
I think you mean 3/5 - 1/2?
we need to make the denominators the same, so we find the LCM of 5 and 2, which is 1, so we multiply them to get a common denominator of 10.
Now we multiply 3/5 by 2/2 to get 6/10, and 1/2 by 5/5 to get 5/10.
6/10 - 5/10 = 1/10
