Question

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

Answer 1

2x+1.....i think,let me know 

Answer 2

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

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`
