1. Problem Description

We need to factor the quadratic expression 6y2+7y36y^2 + 7y - 3.

2. Solution Steps

We are looking for two binomials of the form (Ay+B)(Cy+D)(Ay + B)(Cy + D) such that
AC=6AC = 6, AD+BC=7AD + BC = 7, and BD=3BD = -3.
We can try different combinations of factors for 6 and -

3. Possible factor pairs for 6 are (1, 6) and (2, 3).

Possible factor pairs for -3 are (1, -3) and (-1, 3).
Let's try A=2A = 2 and C=3C = 3, so we have (2y+B)(3y+D)(2y + B)(3y + D).
We need 2D+3B=72D + 3B = 7 and BD=3BD = -3.
If we try B=3B = 3 and D=1D = -1, we get 2(1)+3(3)=2+9=72(-1) + 3(3) = -2 + 9 = 7. This works!
So the factorization is (2y+3)(3y1)(2y + 3)(3y - 1).
Let's check this:
(2y+3)(3y1)=2y(3y)+2y(1)+3(3y)+3(1)=6y22y+9y3=6y2+7y3(2y + 3)(3y - 1) = 2y(3y) + 2y(-1) + 3(3y) + 3(-1) = 6y^2 - 2y + 9y - 3 = 6y^2 + 7y - 3.
This is the correct expression.

3. Final Answer

(2y+3)(3y1)(2y + 3)(3y - 1)
