Question

Determine the factors of 15x2 + 3xy + 10x + 2y. (4 points)

(3x + 2)(5x + y)
(5x + y)(2x + 3)
(3x + y)(5x + 2)
(5x + 3)(2x + y)

Answer 1

the answer is the first option : A

Explanation:

Answer 2

We have to determine the factors of:
15 x² + 3 x y + 10 x + 2 y =
= 3 x · ( 5 x + y ) + 2 · ( 5 x + y ) =
= ( 5 x + y ) ( 3 x + 2 ) = ( 3 x + 2 ) ( 5 x + y )
Answer:
A ) ( 3 x + 2 ) ( 5 x + y )
