Use the FOIL method.
F = First
O = Outer
I = Inner
L = Last
Step 1: Multiply the First terms of each binomial
2x * 2 = 2x^2
Step 2: Multiply the Outer terms
2x * 1 = 2x
Step 3: Multiply the Inner terms
9 * x = 9x
Step 4: Multiply the Last terms of each expression
9 * 1 = 9
Step 5: List the results of FOIL in order
2x^2 + 2x + 9x + 9
Step 6: Combine like terms to get your final answer
2x^2 + 11x + 9
