x, 7 x^{2} + 8 x - 9 = 10

x = \frac{- 4 + 149}{7}, x = - \frac{4 + 149}{7}

Solution steps

7 x^{2} + 8 x - 9 = 10

Move

10

to the left side

7 x^{2} + 8 x - 19 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 7 ( - 19 )}{2 \cdot 7}

8^{2} - 4 \cdot 7 (- 19) = 2149

x_{1, 2} = \frac{- 8 \pm 2 149}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- 8 + 2 149}{2 \cdot 7}, x_{2} = \frac{- 8 - 2 149}{2 \cdot 7}

x = \frac{- 8 + 2 149}{2 \cdot 7} : \frac{- 4 + 149}{7}

x = \frac{- 8 - 2 149}{2 \cdot 7} : - \frac{4 + 149}{7}

The solutions to the quadratic equation are:

x = \frac{- 4 + 149}{7}, x = - \frac{4 + 149}{7}

x^{2} - 7 = - 3 x^{2}

6 y^{2} - y + 2 = 0

3 x^{2} + 10 x - 88 = 0

(x - 6)^{2} - 64 = 0

12 x^{2} - 4 x + 7 = 0
