Answer:
a^2+2ab+b^2
Step-by-step explanation:
FOIL method is First variables Outer variables Inner variables Last variables
(a+b)^2 rewritten is (a+b)(a+b)
F - a*a
O - a*b
I - a*b
L - b*b
a*a+a*b+a*b+b*b
simplify
a^2+2ab+b^2
I think it might be 2x^2 + 2x + 2xy
For this case we can model the problem as a rectangle triangle.
We know:
Length of the sides of the triangle
We want to know:
Length of the hypotenuse
Using the Pythagorean theorem we have:

Rewriting the expression we have:
