8 x^{2} = 7 - 10 x

x = \frac{1}{2}, x = - \frac{7}{4}

Decimal Notation

x = 0.5, x = - 1.75

Solution steps

8 x^{2} = 7 - 10 x

Move

10 x

to the left side

8 x^{2} + 10 x = 7

Move

7

to the left side

8 x^{2} + 10 x - 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 8 ( - 7 )}{2 \cdot 8}

1 0^{2} - 4 \cdot 8 (- 7) = 18

x_{1, 2} = \frac{- 10 \pm 18}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- 10 + 18}{2 \cdot 8}, x_{2} = \frac{- 10 - 18}{2 \cdot 8}

x = \frac{- 10 + 18}{2 \cdot 8} : \frac{1}{2}

x = \frac{- 10 - 18}{2 \cdot 8} : - \frac{7}{4}

The solutions to the quadratic equation are:

x = \frac{1}{2}, x = - \frac{7}{4}

2 x^{2} = \frac{1}{2}

y, 2 x^{3} + 3 y^{2} = 3 x + 7

5 8^{2} = x^{2} + x^{2}

3 x^{2} + 6 x - 5 = 0

- 0.5 x^{2} + 3.2 x + 22 = 0
