Question

To factor the trinomial 2x ^ 2 + 3x + 1 , find factors of what number that add to 3?

Answer 1

Explanation:

2x2 + 3x + 1

First we will multiply 2 by 1 = 2 we have to find the factors of 2 which is just 2 x 1 = 2 that may add or subtract to 3

2x2 + 2x + x + 1

2x ( x + 1) + 1 ( x + 1)

( 2x + 1) and ( x + 1) are the factors
