9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
Set each equation equal to zero.
y + 5 = 0
Subtract 5 from both sides.
y = 0 - 5
y = - 5
y - 9 = 0
Add 9 to both sides
y = 0 + 9
y = 9
y = - 5, 9

I assume you mean:
3x^2 -5xy + 5y^2.
Simply substitute the given values into the equation:
3(-6)^2 - 5(-6)(2) + 5(2)^2
=188
Multiply both sides of the equation by 20, the lowest common denominator of 5,4,2.
Add 4 and 3 to get 7.
Use the distributive property to multiply −4 times x 4/7.
Multiply −4 by 4/7.
