- 8 x^{2} - 14 x + 15 = 0

x = - \frac{5}{2}, x = \frac{3}{4}

Decimal Notation

x = - 2.5, x = 0.75

Solution steps

- 8 x^{2} - 14 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 ( - 8 ) \cdot 15}{2 ( - 8 )}

(- 14)^{2} - 4 (- 8) \cdot 15 = 26

x_{1, 2} = \frac{- ( - 14 ) \pm 26}{2 ( - 8 )}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 26}{2 ( - 8 )}, x_{2} = \frac{- ( - 14 ) - 26}{2 ( - 8 )}

x = \frac{- ( - 14 ) + 26}{2 ( - 8 )} : - \frac{5}{2}

x = \frac{- ( - 14 ) - 26}{2 ( - 8 )} : \frac{3}{4}

The solutions to the quadratic equation are:

x = - \frac{5}{2}, x = \frac{3}{4}

- 3 x^{2} + 3 x + 60 = 0

x^{2} - 15 x - 20 = 0

x^{2} - 6 = 43

g, 3 = N g^{2} - Q

t^{2} + 5 t - 6 = 0
