3 * 3 * 5 * x * y * y = 45xy2
The compound with the formula XY2 consists of one atom of element X and two atoms of element Y.

(x4 + y4)/(x + y) = Quotient = x3 - x2y + xy2 - y3 Remainder = - 2y4/(x+y) So, x3 - x2y + xy2 - y3 - 2y4/(x+y)
15x2y2-9xy3 As x2y2 = x xy2 and xy3 = xy2 y then xy2 is in both term you can first factorize 15x2y2-9xy3 = xy2(15x-9y) as 15=3x5 and 9=3x3 15x2y2-9xy3 = 3xy2(5x-3y) and that it !
2 x 3 = 6 2 x 2 x 3 = 12 3 x 5 = 15
1 x 12 2 x 6 3 x 4
2 x 2 x 3
When you're solving for the x intercept, y=0. For example, if you have a question like 3y-4x=12, and you want to find the x intercept, you substitute 0 for y. Like this: 3y-4x=12 3(0)-4x=12 -4x=12 -4x/-4=12/-4 x=-3 The x intercept is -3
47 2 x 2 x 3 = 12 2 x 2 x 3 x 47 = 564, the LCM
x2-7x+12 (x-3)(x-4)
3+4x=15 4x=15-3 4x=12 x=12/4 x=3 The check is: If x=3 then, 3+ (4 X 3)=15 3+12=15
