Hi there! In order to factor, start by knowing the variables for each term in the equation ax^2+bx+c A=1 B=-5 C=4 (Based on the given equation) In order to factor, we need to find two numbers that add to the b term (-5) but multiply to the c term (4) -4*-1=4 -4+-1=-5 Therefore, the factored form would be y=(x-4)(x-1)
