(x+3y)(_____ )=9y^2 -x^2.

(x+3y)(_____ )=9y^2 -x^2.


Square difference formula (x + 3Y) (3y-x) = 9y ^ 2 - x ^ 2



What is (x + 3Y) (3y-1) = 9y ^ 2 + X equal to?


It is reduced to 3Y (1-1 / x) = 2
The title should be an integer, then x = 3, y = 1



X^2-9Y^2+3Y-X


x²-9y²+3y-x=(x+3y)(x-3y)-(x-3y)=(x-3y)(x+3y-1)



Factorization factor X ^ 2-x-9y ^ 2-3y
And this 12 (x + y) ^ 2 + 11 (x ^ 2-y ^ 2) + 2 (X-Y) ^ 2


x^2-x-9y^2-3y
=(x^2-9y^2)-x-3y
=(x+3y)(x-3y)-(x+3y)
=(x+3y)(x-3y-1)
