Multiply the 2 binomials using FOIL:
(x + 7)(x - 5)
Define FOIL Formula:
First-Outside-Inside-Last:
(a + b)(c + d) = (a * c) + (b * c) + (a * d) + (b * d)
Set our FOIL values:
a = x, b = 7, c = x, and d = -5
Evaluate:
(x + 7)(x - 5) = (x * x) + (7 * x) + (x * -5) + (7 * -5)
(x + 7)(x - 5) = x2 + 7x - 5x - 35
x2 + 2x - 35
You have 2 free calculationss remaining
What is the Answer?
x2 + 2x - 35
