STEP1:Equation at the end of step 1
5x2 - (2x + 4) = 0
STEP2:Trying to factor by splitting the middle term
Factoring 5x2-2x-4
The first term is, 5x2 its coefficient is 5 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 5 • -4 = -20
Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -2 .
-20 + 1 = -19
-10 + 2 = -8
-5 + 4 = -1
-4 + 5 = 1
-2 + 10 = 8
-1 + 20 = 19
