x^{2} - 10 = 9 x

x = 10, x = - 1

Solution steps

x^{2} - 10 = 9 x

Move

9 x

to the left side

x^{2} - 10 - 9 x = 0

Write in the standard form

a x^{2} + b x + c = 0

x^{2} - 9 x - 10 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot ( - 10 )}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot (- 10) = 11

x_{1, 2} = \frac{- ( - 9 ) \pm 11}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 11}{2 \cdot 1}, x_{2} = \frac{- ( - 9 ) - 11}{2 \cdot 1}

x = \frac{- ( - 9 ) + 11}{2 \cdot 1} : 10

x = \frac{- ( - 9 ) - 11}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

x = 10, x = - 1

∣ 7 v - 4 ∣ = - 14
