Hope this helps :)

Answer 2

Answer:

(-3 + -2y)(5 + -1y) = 0

Step-by-step explanation:

Simplifying

(y + -5)(2y + 3) = 0

Reorder the terms:

(-5 + y)(2y + 3) = 0

Reorder the terms:

(-5 + y)(3 + 2y) = 0

Multiply (-5 + y) * (3 + 2y)

(-5(3 + 2y) + y(3 + 2y)) = 0

((3 * -5 + 2y * -5) + y(3 + 2y)) = 0

((-15 + -10y) + y(3 + 2y)) = 0

(-15 + -10y + (3 * y + 2y * y)) = 0

(-15 + -10y + (3y + 2y2)) = 0

Combine like terms: -10y + 3y = -7y

(-15 + -7y + 2y2) = 0

Solving

-15 + -7y + 2y2 = 0

Solving for variable 'y'.

Factor a trinomial.

(-3 + -2y)(5 + -1y) = 0
