(x + y)(x10 - x9y + x8y2 - x7y3+ x6y4 - x5y5 + x4y6 - x3y7 + x2y8 - xy9 + y10)
-12 x8 y8 / 3x4 y2 = -4 x4y6 First: divide -12 by 3 which equals -4 Second: divide x to the power of 8 by x to the power of 4 by subtracting the two powers ( 8-4 ) which will equal x to the power of 4 Third: divide y to the power of 8 by y to the power of 2 by subtracting the two powers ( 8-2 ) which will equal y to the power of 6
