g^{2} - 9 g - 65 = 5

g = 14, g = - 5

Solution steps

g^{2} - 9 g - 65 = 5

Move

5

to the left side

g^{2} - 9 g - 70 = 0

Solve with the quadratic formula

g_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot ( - 70 )}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot (- 70) = 19

g_{1, 2} = \frac{- ( - 9 ) \pm 19}{2 \cdot 1}

Separate the solutions

g_{1} = \frac{- ( - 9 ) + 19}{2 \cdot 1}, g_{2} = \frac{- ( - 9 ) - 19}{2 \cdot 1}

g = \frac{- ( - 9 ) + 19}{2 \cdot 1} : 14

g = \frac{- ( - 9 ) - 19}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

g = 14, g = - 5

x^{2} + x - 30 = 0

9 x^{2} = 6 x - 4

(x - 8)^{2} = 100

x^{2} + 4 x - 32 = 0

x^{2} - 108 = 0
