Question

Expand and simplify (X+5)(X+1)

Answer 1

Explanation:

(X+5)(X+1) = x²+x+5x+5 = x² +6x+5

Answer 2

(X+5)(X+1)

Use the FOIL method to expand.

This means multiply each term in the first set of parenthesis by each term in the second set.

x *x = x^2

x*1 = x

5*x = 5x

5*1 = 5

Now you have x^2 + x + 5x + 5

Now simplify by combining like terms:

x^2 + 6x + 5
