Answer:
Step-by-step explanation:
did u ever hear of the FOIL method ?
First, outside, inside, last
(5x + 2)(x + 1)
FIRST: multiply the first terms in each set : 5x * x = 5x^2
OUTSIDE: multiply outside terms in each set : 5x * 1 = 5x
INSIDE:multiply inside terms in each set: 2 * x = 2x
LAST: multiply last terms in each set: 2 * 1 = 2
so we now have : 5x^2 + 5x + 2x + 2....combine like terms
5x^2 + 7x + 2 <== ur answer
