(7y + 2)(7y - 2)
4
52 is not a factor of 325. 5 squared is a factor of 325.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The ones that are squares are 1 and 4.
(b + 2c)(b - c)
2X^2 - 32 = 0 2X^2 = 32 X^2 = 16 X = +/- 4 yes, (X-4) would be a factor, as...... x-4 = 0 X = 4 or 2x2 - 32 = 2(x2 - 16) = 2(x - 4)(x + 4)
This is a difference of two sqaures. 49y2 - z2 = (7y - z)(7y + z)
The GCF is 4.
9xy(3xy - 4)
73y + 144y + 49y=266y
4 squared is 16. 4 squared means that 4 is used as a factor 2 times. 4x4=16
Yes.
7
(3x-4)(3x+4)
25x2-49y2 is the difference of two squares and can be factored as:- (5x-7y)(5x+7y)
-4
x(x-4)
(a + 2 - b) (a + 2 + b)
