Question

Which expression is a factor of 10x2 + 11x + 3?

Answer 1

Answer:

$(2x+1)(5x+3)$

Step-by-step explanation:

Given : $10x^2 + 11x + 3$

To Find: Factors

Solution:

$10x^2 + 11x + 3$

$10x^2 +6x+5x + 3$

$2x(5x+3) +1(5x + 3)$

$(2x+1)(5x+3)$

Thus  $(2x+1)(5x+3)$ is a factor of given expression.

Hence the expression  $(2x+1)(5x+3)$  is a factor of $10x^2 + 11x + 3$
