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.

(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.
Oh, what a happy little question we have here! To find the factors of 18xy, we need to break it down into its smallest parts. The factors of 18 are 1, 2, 3, 6, 9, and 18, while the factors of x and y are just x and y themselves. So, the factors of 18xy are 1, 2, 3, 6, 9, 18, x, y, 2x, 3x, 6x, 9x, 18x, xy, 2y, 3y, 6y, 9y, and 18y.

(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.
