Question

How do you multiply polynomials `(-5x)(2x²-3)-4x`?

Answer 1

Multiply the `-5x` into `2x^2` and `-3`

Explanation:

First we multiply `-5x` into the `(2x^2-3)` by distributing the terms. (Use B.E.D.M.A.S )
`(-5x*2x^2)+(-5x*-3)-4x`
then we have
`(-10x^3)+(15x)-4x`
now collect like terms
`-10x^3+11x`
