(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+7)(x−4)

=(x+7)(x+−4)

=(x)(x)+(x)(−4)+(7)(x)+(7)(−4)

=x^2−4x+7x−28

=x^2+3x−28

F(x)=2x+1 and g(x)=x^2-7, find (f g) (x)
hodyreva [135]

The answer is (f o g)(x) = 2x^2 - 13

In order to find a composite function, you take the first letter (in this case f) and use that equation. You then remove the variable and put in the second letter (g).

f(x) = 2x + 1 ----> Remove variable.

f(x) = 2(      ) + 1 ----> Insert g(x)

(f o g)(x) = 2(x^2 - 7) + 1 ----> Distribute

(f o g)(x) = 2x^2 - 14 + 1 ----> Simplify

(f o g)(x) = 2x^2 - 13
