Question

Expand the following x(x-6), x(4x-1), 2x(5x+4), 3x(5x-y)

Answer 1

a.
`{x}^(2) - 6x`

b.
`4 {x}^(2) - x`

c.
`10 {x}^(2) + 8x`

D.
`15 {x}^(2) - 3xy`

Explanation:

a.

`x(x - 6)`

Multiply each term in the parentheses by X

`x * x - x * 6`

Calculate

`{x}^(2) - 6x`

b.

`x(4x - 1)`

Multiply each term in the parentheses by X

`x * 4 - x * 1`

Calculate

`4 {x}^(2) - x`

c.

`2x(5x + 4)`

Multiply each term in the parentheses by 2x

`2x * 5x + 2x * 4`

Calculate

`10 {x}^(2) + 8x`

d.

`3x(5x - y)`

Multiply each term in the parentheses by 3x

`3x * 5x - 3x * y`

Calculate

`15 {x}^(2) - 3xy`

Hope this helps..

Good luck on your assignment

Answer 2

x^2-6x, 4x^2-1x,10x^2+8x,15x^2-3xy

Just use the distributive property like you have before and you will get these answers, Hope this helped!
