Answer 1

The answer is x=
`(9+√(69))/(2)`, x=
`(9-√(69))/(2)`

Explanation:

x^2=a

-9x=b

3=c

Plug into formula.

Equation:
`(9+-√((-9)^2-4(1)(3)))/(2)`

Simplify the equation.

Equation:
`(9+-√(81-12))/(2)`

Subtract 81 and 12.

Equation:
`(9+-√(69))/(2)`

Spit into two equations

Equation 1:
`(9+√(69))/(2)`

Equation 2:
`(9-√(69))/(2)`

Hope this helps!
