Question

Multiply the following polynomials(2x^2+4x-3)(5x-6)

Answer 1

Answer:
`10x^3+14x^2-39x+18`Explanations:

The given expression is:

`(2x^2+4x-3)\text{ (5x - 6)}`

The terms in the first bracket multiply each of the terms in the second bracket one after the other

`(2x^2)(5x)-(2x^2)(6)+(4x)(5x)-4x(6)-3(5x)-3(-6)`

The expression then becomes:

`10x^3-6x^2+20x^2-24x-15x+18`

By combining like terms, the final expression then becomes:

`10x^3+14x^2-39x+18`
