x2-49 = (x-7)(x+7)
How do you find the solution to x2 - 20xy plus 4y2?
If you're looking to factor this expression, then you need to find two values that add up -20, and which multiply to make 4. Unfortunately, no such terms exist, so this expression can not be factored.
How do you factor 2x2-8y2?
First it would be easiest to factor out the 2. 2x2-8y2 2(x2-4y2) Then you factor the part in the parenthesis as follows 2(x-2y)(x-2y) which can be simplified as 2(x-2y)2
X2 plus 3xy - 18y2 equals?
(x + 6y)(x - 3y)
How do you factor x2-8x equals 16 completely?
L2 math.
Factor x2 plus 13x plus 36 completely?

In solving polynomials x cubed plus 8 y cubed?
x3+8y3 = (x+2y)(x2-2xy+4y2) The discriminant of the quadratic factor is 4y2-16y2 < 0 so there are no real roots. So the only real root of the original polynomial is x+2y=0 or x = -2y
