Quadratic trinomals are in the form of x^2+bx+c
You need to find the factors of c that add up to b.
So the first question x^2+5x-14
You are looking for the factors (multiply) of -14 that add up to 5
You need to do the same for the next one. Factors of 3 that add up to -4
Those factors would be -3 and -1
That makes the factors (x-1)(x-3)
