$3x^2$ +11x + 8
Work Step by Step
(3x+8)(x+1) Use FOIL to simplify. FOIL: First (Multiply the first variables in the brackets), outside (Multiply the outer variables), Inside (Multiply the inside variables), Last (Multiply the last variables in the brackets). $3x^2$ +3x + 8x + 8 $3x^2$ +11x + 8 Foil method is more efficient as it is faster and more comprehensible.
