- 7 x^{2} = - 5 x - 2 x^{2} - 7 x^{2} + 5 + 9 x + 2 + 4 x + 3

x = - 1, x = 5

Solution steps

- 7 x^{2} = - 5 x - 2 x^{2} - 7 x^{2} + 5 + 9 x + 2 + 4 x + 3

Refine

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

Switch sides

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

Move

7 x^{2}

to the left side

- 2 x^{2} + 8 x + 10 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 ( - 2 ) \cdot 10}{2 ( - 2 )}

8^{2} - 4 (- 2) \cdot 10 = 12

x_{1, 2} = \frac{- 8 \pm 12}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 8 + 12}{2 ( - 2 )}, x_{2} = \frac{- 8 - 12}{2 ( - 2 )}

x = \frac{- 8 + 12}{2 ( - 2 )} : - 1

x = \frac{- 8 - 12}{2 ( - 2 )} : 5

The solutions to the quadratic equation are:

x = - 1, x = 5

3 x^{2} - 10 x - 32 = 0

- x^{2} - 8 x - 12 = 0

x, x^{2} - k x + 81 = 0

- 5 x^{2} + 10 x + 35

x^{2} - x - 1 = 0
