Question

Helpppppppp meeeeeee

Answer 1

`4x^5-5x^3-6x`

Explanation:

Given:
`(x^3-2x)(4x^2+3)`

To find: the product

Solution:

Use the property: Multiplication is distributive over addition that is
`a(b+c)=ab+ac`

`\left ( x^3-2x \right )\left ( 4x^2+3 \right )=(x^3-2x)4x^2+(x^3-2x)3\\=4x^5-8x^3+3x^3-6x`

Add the like terms:
`-8x^3,3x^3`

(Like terms are terms that have same variables of same powers)

So,

`\left ( x^3-2x \right )\left ( 4x^2+3 \right )=(x^3-2x)4x^2+(x^3-2x)3\\=4x^5-8x^3+3x^3-6x\\=4x^5-5x^3-6x`
