4 - y2 can be written as 22 - y2. This has become of the form of x2 - y2.
Expansion for x2 - y2 is (x+y)(x-y).
So, 4 - y2 = 22 - y2 = (2+y)(2-y)
The greatest common factor in the two terms is [ 4y ].The factored form of the expression is4y (y + 7x)
The GCF of 4y and 12 is 3.
(y - 1)(3y + 7)
(z - 4)(x + y)
Factor out a 2; so it is 2(x+2y).
factor 4y - 32
(3 - 4y)(3 + 4y)
The GCF is 4y.
(4y - 1)(16y2 + 4y + 1)
The greatest common factor in the two terms is [ 4y ].The factored form of the expression is4y (y + 7x)
The GCF of 4y and 12 is 3.
x2 -y2 +4y-4=(x+y)(x-y)+4y-4
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
4y(68y - 9x)
4y
It is: 3(5x-4y)
Factor out the 4. The answer is y-3/y+3
