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
