If by "What is the answer to", you mean "How do you factor", then we can solve it as follows:
x2 + 13xy + 36y2
= x2 + 4xy + 9xy + 36y2
= x(x + 4y) + 9y(x + 4y)
= (x + 9y)(x + 4y)
x2 − 36y2
x2 = 18y2/5 + 10 Or if you want to isolate x: x = ± √(18y2/5 + 10)
4(2x + 3y)(2x + 3y)
(3x - 7y)(2x + 9y)
X4y6
The GCF is 13xy.
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
15xy-2xy-7x+x=13xy-6x
x2 + x2 = 2x2
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x2 + 48x + 320
x2 + x2 = 2x2
