Short Answer

Expert verified

The factored form is(2a+3)(a+1)

Step by step solution

01

Given information

Given the polynomial2a2+5a+3

02

Write the factors of the first term

The first term is 2a2, the factors are 2a,1a, putting in parentheses, we get

(2a)(a)

03

Calculating the factors of the third term

The third term is 3, the factors is 1,3so testing the possible combinations, we have2,3

(2a+3)(a+1)=2a2+5a+3
