use the quadratic formula and plug in the coefficients


3x - 9 {x}^(2) = - 10 \\ - 9 {x}^(2) + 3x + 10 = 0 \\ b = 3 \\ a = - 9 \\ c = 10 \\ - \frac{3 + \sqrt{ {3}^(2) - 4( - 9)(10) } }{2( - 9)} \\ ( - 3 + √(9 + 360) )/( - 18) \\ \frac{ - 3 + 3 √(41) }{{ - 18} } \\ ( - 1 + √(41) )/( - 6)

I wasn't able to the plus or minus sign in so I just used the plus sign you can look up the quadratic formula online
