Question

Factor completely: 10x^2 + 2xy + 15x + 3y

Answer 1

take first 2 terms 10x^2 + 2xy
what can you factor out from this ?

Answer 2

This problem required factoring by grouping.

Group the first two and last two terms to get:
(10x^2 + 2xy) + (15x + 3y).

Factor out the GCFs from each pair of terms to get:
2x(5x + y) + 3(5x + y).

Then, factoring out the 5x + y yields:
(2x + 3)(5x + y).

Therefore, the answer is (A) (2x + 3)(5x + y).

I hope this helps!

Answer 3

how did you know that choice A is (2x + 3)(5x + y).
