Question

Perform the indicated operation to write given polynomial in standard form: (x+ 2)(2x^2 − 5x+7)

Answer 1

So the expression in standard form will be
`2x^3-x^2-3x-14`

Explanation:

We have given expression
`(x+2)(2x^-5x+7)`

We have to write this expression in standard form

For writing in standard form first we have to multiply the expression

So after multiplication number
`(x+2)(2x^2-5x+7)=2x^3-5x^2+7x+4x^2-10x-14=2x^3-x^2-3x-14`

So the expression in standard form will be
`2x^3-x^2-3x-14`
