Question

Multiply the polynomials (7x^2+5x+7)(4x-6)

Answer 1

28x^3 - 22x^2 - 2x -42

Answer 2

The simplified solution is
`28x^(3)-22x^(2)-2x-42`

Explanation:

we need to multiply the given expression;

`(7x^(2)+5x+7)(4x-6)`

we will multiply term wise

`7x^(2)(4x-6)+5x(4x-6)+7(4x-6)`

`(7x^(2)* 4x)-(7x^(2)* 6)+(5x* 4x)-(5x* 6)+(7* 4x)-(7* 6)`

`28x^(2+1)-42x^(2)+20x^(2)-30x+28x-42`

`28x^(3)-22x^(2)-2x-42`

The simplified solution is
`28x^(3)-22x^(2)-2x-42`
