Answer 19

I am not that sure but i think it is the first one

Answer 20

first step, I can write this:
\[4{x^2} + 12x - 16 = 4\left( {{x^2} + 3x - 4} \right)\]
now we have to factorize the subsequent polynomial: \({{x^2} + 3x - 4} \)
In order to do that, we have to find two numbers, such that their sum is equal to \(-3\) and their product is equal to \(-4\)
please try to find such numbers
