The first one would be x^12
(x^4 - 9)(x^3 + 9)
This is a binomial * binomial. Use the FOIL method for multiplying.
First, outer, inner, last.
x^4 * x^3 = x^7
x°^4 * 9 = 9x^4
-9 * x^3 = -9 x^3
-9 * 9 = -81
Putting it back together.
x^7 +9x^4 -9x^3 - 81
-6(1+7x)+7(1+6x)=-2
This is False.
Use distributive property:
-6 -42x + 7 +42x = -2
Combine like terms to get:
1 = -2
Since 1 is not -2, it is false.
Your anwer is going to be 314 with 101 0s behind it
