Question

(x+7)(x+9) Do this math problem by using the Foil method.​

Answer 1

Answer:

Step-by-step explanation:

F: x * x  = x^2

O:9 * x = 9x

I : 7 * x = 7x

L: 7 * 9 = 63

x^2 + 9x + 7x + 63

x^2 + 16x + 63

Answer 2

Foil:
First term
Outer term
Inner term
Last term

By using foil we just times the first terms together so: x*x=x^2

Then we times the outer terms together so: x*9=9x

Then we times the inner terms together so:7*x=7x

Finally we times the last terms together so: 7*9=63

So our equation is:
X^2+9x+7x+63

Now we collect the like terms

Answer: x^2+16x+63
