Trying to factor by splitting the middle term
3.1 Factoring -4x2+2x+7
The first term is, -4x2 its coefficient is -4 .
The middle term is, +2x its coefficient is 2 .
The last term, "the constant", is +7
Step-1 : Multiply the coefficient of the first term by the constant -4 • 7 = -28
Step-2 : Find two factors of -28 whose sum equals the coefficient of the middle term, which is 2 .
-28 + 1 = -27
-14 + 2 = -12
-7 + 4 = -3
-4 + 7 = 3
-2 + 14 = 12
-1 + 28 = 27
Answer:-4x2 + 2x + 7
