Question

`4 {x}^(2) - 2x + x = 5 {x}^(2) + 2x \\ find \: the \: value \: of \: x`

fast please no wrong answer​

Answer 1

`\rm x = -3`

Explanation:

`\rm 4 {x}^(2) - 2x + x = 5 {x}^(2) + 2x`

`\rm 4x^(2)-x=5x^(2)+2x`

`\rm 4x^(2)-x-5x^(2)=2x`

`\rm -x^(2)-x=2x`

`\rm -x^(2)-x-2x=0`

`\rm -x^(2)-3x=0`

`\rm -x-3=0`

`\rm x = 3 / (-1)`

`\bold{x = -3}`

Answer 2

`4 {x}^(2) - 2x + x = 5 {x}^(2) + 2x \\ 4 {x}^(2) - x = 5 {x}^(2) + 2x \\ 4 {x}^(2) - 5 {x}^(2) = 2x + x \\ - 1 {x}^(2) = 3x \\ - x = 3 \\ x = - 3 \\ thank \: you`
