(x + 7) (x - 4)

First, apply the FOIL method (a + b) (c + d) = ac + ad + bc + bd / Your problem should look like: x^{2} - 4x + 7x - 28
Second, gather the like terms. / Your problem should look like: x^{2} + (-4x + 7x) - 28
Third, simplify. / Your problem should look like: x^{2} + 3x - 28

Answer: x^{2} + 3x - 28

=(x)(x)+(x)(−4)+(7)(x)+(7)(−4)

=x^2−4x+7x−28

=x^2+3x−28
