Factoring 40x2y+44xy24y40x^2y + 44xy - 24y

Factor 40x2y+44xy24y40x^2y + 44xy - 24y completely by first extracting the greatest common factor and then factoring the resulting trinomial.

Step 1 — Check for a GCF: The terms share a greatest common factor of 4y4y. Factor it out: 4y(10x2+11x6)4y(10x^2 + 11x - 6)

Step 2 — Classify the expression: The expression inside the parentheses is a trinomial with a leading coefficient other than 11 (a1a \neq 1). Factor it using the trial and error or "ac" method.

Step 3 — Factor the trinomial: Using the preferred method, we find the binomial factors: 4y(5x2)(2x+3)4y(5x - 2)(2x + 3)

Step 4 — Check: Verify by multiplying: 4y(5x2)(2x+3)=4y(10x2+15x4x6)=4y(10x2+11x6)=40x2y+44xy24y4y(5x - 2)(2x + 3) = 4y(10x^2 + 15x - 4x - 6) = 4y(10x^2 + 11x - 6) = 40x^2y + 44xy - 24y

The completely factored form is 4y(5x2)(2x+3)4y(5x - 2)(2x + 3).
