Question

Help to solve quadratic formula and round to nearest hundredth

Answer 1

x1 = 2.86

x2 = -0.53

Explanation:

`a=6, b=-4, c=-9`

`x=\frac{-(-14)+-\sqrt{(-14)^(2)-4(6)(-9) } }{2(6)}`

`x=(14+-√(412) )/(6)`

`x=(14+-20.3)/(12)`

`x_(1) =(14+20.3)/(12) =2.86`

`x_(2) =(14-20.3)/(12) =-0.525`

Hope this helps
