Question

Rewrite each polynomial in standard form by applying the operations in the appropriate order: (x^2 − 4)(x +3) − (x^2 +2x − 5)

Answer 1

in standard form polynomial will be
`x^3+2x^2-6x-7`

Explanation:

We have given equation
`(x^2-4)(x+3)-(x^2+2x-5)`

We have to write this in standard form

For writing in standard form first we have to multiply and then subtract

So
`(x^2-4)(x+3)-(x^2+2x-5)=x^3-4x+3x^2-12-x^2-2x+5=x^3+2x^2-6x-7`

So in standard form polynomial will be
`x^3+2x^2-6x-7`
