x^{2} + 12 x - 70 = 9 x

x = 7, x = - 10

Solution steps

x^{2} + 12 x - 70 = 9 x

Move

9 x

to the left side

x^{2} + 3 x - 70 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot ( - 70 )}{2 \cdot 1}

3^{2} - 4 \cdot 1 \cdot (- 70) = 17

x_{1, 2} = \frac{- 3 \pm 17}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 3 + 17}{2 \cdot 1}, x_{2} = \frac{- 3 - 17}{2 \cdot 1}

x = \frac{- 3 + 17}{2 \cdot 1} : 7

x = \frac{- 3 - 17}{2 \cdot 1} : - 10

The solutions to the quadratic equation are:

x = 7, x = - 10

2 c^{2} + 3 c - 1 = 0

λ^{2} - 5 λ + 6 (1) = 0

x^{2} - 2 x = 2 x + 12

x^{2} - 11 x + 15 = 0

4 y^{2} - 3 = 0
