We are missing an important sign (+/-)
I shall assume
9x2 - 18xy + 9y2
9(x-y)(x-y)
To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
Factor: 9x2 - 25.
63
(4x + 3y)(4x + 3y) or (4x + 3y)2
9x2 + 9x - 10 =(3x - 2)(3x + 5)
To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
(3x - y)(3x - 5y) and (2x + 1)(2x + 11)
This is an expression, not an equation. Expressions cannot be solved.
Factor: 9x2 - 25.

(x + 3y)(x2 - 3xy + 9y2)
18xy is the GCF of 72x2y and 18xy
y(x - 9)(x - 9)
It is -18xy
is 9x^2 + 4 prime factor
The GCF is 9.
(4x + 3y)(4x + 3y) or (4x + 3y)2
