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)
