Question

Factor completely 5x(x + 3) + 6(x + 3).

(x + 3)(30x)

(x + 3)(5x + 6)

(x + 3)(11x)

Prime

Answer 1

5x(x+3)+6(x+3) = (5x+6) (x+3) = (x+3)(5x+6)

Answer 2

Option 2 is correct.

Explanation:

Given the expression 5x(x + 3) + 6(x + 3).

We have to factorize the expression completely.

Expression is

5x(x + 3) + 6(x + 3)

Take the factor (x+3) common from both the terms, we get

(x+3)(5x+6)

Hence, option 2 is correct.
