x2 + 10y + 25 doesn't factor neatly. If that was x2 + 10x + 25, it would factor to (x + 5)(x + 5) or (X + 5)2
y + x = 9 10y + 20x = 100 This is a basic linear system of equalities. We can start by rewriting the first equation as: -10y - 10x = -90 by multiplying the equation by -10, from here we can eliminate y and solve for x (-10y - 10x = -90) + (10y + 20x = 100) = (10x = 10) This yields x = 1, and by plugging x into the first equation y = 8
X=7 y=5

10y plus 40 equals 50y.

y - intercept = 10x - intercept = -10y- intercept: x = 0y = x + 10y = 0 + 10y = 10x - intercept: y = 0y = x + 100 = x + 10x + 10 = 0x = -10

The greatest common factor of 10y plus 15 is 5.
5x(x - 2) + 5y(x - 2) = (5x + 5y)(x - 2) = 5(x - 2)(x + y)

10y plus 40 equals 50y.
Clearly, both terms have 5 as a factor. If you divide by 5, you get the other factor:5+10y = 5(1 + 2y)This can't be further factored.
