5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2
Vinvika [58]
5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2

16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:

Multiply the numbers 16 x 2

16 x 2 = 32

Now multiply the numbers 4 x 2

4 x 2 = 8

Now Multiply the numbers 4 x 2 again

4 x 2 = 8

= 32xy - 8x- 8y

Factor 8 from the expression


Final Answer:
8(4xy-x-y)

I’m not really sure about my answer but i hope it helps!
