Simplify (x+7)(x+4)
Apply FOIL method to multiply the expression
First Outer Inner and Last
First : x * x = x^2
Outer : x * 4 = 4x
Inner : 7 * x = 7x
Last : 7 * 4= 28
Now we write all the terms down and combine like terms
[tex]x^2 + 4x + 7x + 28[/tex]
[tex]x^2 + 11x + 28[/tex]
We simplified it completely
[tex]x^2 + 11x + 28[/tex]
