Question

(x2 + 4x) - 2x = x2 +
X

Answer 1

`x=0`

Explanation:

`x^2+4x-2x=x^2+x`

Combine like terms.

`x^2+2x=x^2+x`

Add
`-x^2` and
`-2x` on both sides.

`x^2+2x-x^2-2x=x^2+x-x^2-2x`

`0=x-2x`

`0=-1x`

Divide both sides by
`-1`.

`(0)/(-1) =(-1x)/(-1)`

`0=x`

Answer 2

x=0

Explanation:

(x^2 + 4x) - 2x = x^2 +x

Combine like terms

x^2 +2x = x^2 +x

Subtract x^2 from each side

2x =x

Subtract x from each

2x-x = x-x

x = 0
