Answer: x^2+10x+5x+50 = x^2+15x+50
Step-by-step explanation:
Basically, use something called FOIL. It stands for first, outer, inner, last. Basically multiply the first x, by the first x in the second parenthesis. Then multiply that x by the outer x in the second parenthesis. After that, multiply the 5 by the inner x. Then the five by the ten.
Answer
x²+15x+50
Step-by-step explanation:
You start with the left side of the equation. Multiply the right binomial by x
{ x (x) + x(10) } = x² + 10x
Then multiply the right side of the equation by 5
{ 5 (x) + 5 (10) = 5x + 50
Add both the (x² + 10x) and the (5x+50)
This will give you an answer of x²+15x+50
