the sum of two binominals is

5x squared - 6x. if one of the binominals is 3x squared - 2x, wht is the other binominal?

Subtract the second binomial from the first.

5x2 - 6x - 3x2 +2x

Combine the like terms:

(5x^2 - 3x^2) + (-6x + 2x)

Simplify:

2x^2 - 4x

Therefore, the other binomial is 2x^2 - 4x.
