First, let's find the greatest common factor (GCF) of the terms -45y^2 and 40y.
The GCF of two numbers is the largest number that divides both numbers evenly.
The factors of -45 are -1, 1, -3, 3, -5, 5, -9 and 9.
The factors of 40 are -1, 1, -2, 2, -4, 4, -5, 5, -8, 8, -10 and 10.
The common factors of -45 and 40 are 1 and 5.
So, the GCF of -45y^2 and 40y is 5y.
Now let's factor out the GCF:
-45y^2 + 40y
= 5y(-9y + 8)
Therefore, the factored form of -45y^2 + 40y is 5y * ( -9y + 8)
Find the GCF and then factor.
−45y2+40y
