Answer= x²+7x+10
When we want to expand expressions such as this, the FOIL method helps us remember what exactly to do. FOIL stands for
F:First
O:Outer
I:Inner
L:Last
So, given the expression (x+5)(x+2), lets multiply the first two terms.
x*x=x²
now the outer two terms
x*2=2x
now the inner terms
5*x=5x
and the last terms...
5*2=10
When we combine these expressions we get:
x²+7x+10
I think this is what you meant to be answered in your question, if I have been mistaken, just comment and I'll edit my answer....
Answer:
The student was wrong. The probability is actually 1/4.
Step-by-step explanation:
Let's say you have question A and question B. You could have incorrect on A, and incorrect on B. Or, you could have incorrect on A, but a correct on B. Or, you could have an incorrect on B, but a correct on A. Or, both could be correct. <em><u>Since there are 4 different possibilities, the actual probability is 1/4.</u></em>
