Question

Find


`value \: of \: x \\ 4 {x}^(2) + 5x + 6x = 3x - 2 {x}^(2) + x \\`
fast please ​

Answer 1

`\rm x = -(7)/(6)`

Explanation:

`\rm 4 {x}^(2) + 5x + 6x = 3x - 2 {x}^(2) + x`

`\rm 4x^(2)+11x=3x^(1)-2x^(2)+x`

`\rm 4x^(2)+11x=3x-2x^(2)+x`

`\rm 4x^(2)+11x=4x-2x^(2)`

`\rm 4x^(2)+11x-4x=-2x^(2)`

`\rm 4x^(2)+7x=-2x^(2)`

`\rm 4x^(2)+7x+2x^(2)=0`

`\rm 6x^(2)+7x=0`

`\rm 6x + 7 = 0`

`\bold{x = -(7)/(6)}`

Answer 2

Explanation:

`4 {x}^(2) + 5x + 6x = 3x - 2 {x}^(2) + x \\ 4 {x}^(2) + 11x = 4x - 2 {x}^(2) \\ 4 {x}^(2) + 2 {x}^(2) = 4x - 11x \\ 6 {x}^(2) = - 7x \\ 6x = - 7 \\ x = ( - 7)/(6) \\ thank \: you`
