Question

Simplify: —2xy(—3xy2 + 4x2y)

Answer 1

6x^2y^3 - 8x^3y^2 = 2x^2y^2(3y-4x)

Answer 2

the coefficients in each term can be simplified
-3xy2 = -6xy
4x2y = 8xy

Answer 3

-4 * x^2 * y^2 * (-3 + 4)

Answer 4

or, you can pull a -2xy out of each term in the parens
(-2xy)^2 * (3 - 4)

Answer 5

His 2's are exponents, they all do that in here cos they don't know how...

Answer 6

oh. dammit.

Answer 7
