Question

Solve -7x^2+x+9=-6x quadratic formula

Answer 1

`-7x^2+x+9=-6x`

`-7x^2+x+9+6x=-6x+6x`

`-7x^2+7x+9=0`

`quadratic\: formula`

`x_(1,\:2)=(-7\pm √(7^2-4\left(-7\right)\cdot \:9))/(2\left(-7\right))`

`\sqrt{-7^(2) -4(-7)*9} =√(301)`

`x_(1,\:2)=(-7\pm √(301))/(2\left(-7\right))`

`(-7+√(301))/(2\left(-7\right))`

`=(-7+√(301))/(-2\cdot \:7)`

`=(-7+√(301))/(-14)`

`(-7-√(301))/(2\left(-7\right))`

`=(-7-√(301))/(-2\cdot \:7)`

`=(-7-√(301))/(-14)`

`answer=(7+√(301))/(14)`
