14 x^{2} - 31 x + 15 = 0

x = \frac{3}{2}, x = \frac{5}{7}

Decimal Notation

x = 1.5, x = 0.71428 \dots

Solution steps

14 x^{2} - 31 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 31 ) \pm ( - 31 ) ^{2} - 4 \cdot 14 \cdot 15}{2 \cdot 14}

(- 31)^{2} - 4 \cdot 14 \cdot 15 = 11

x_{1, 2} = \frac{- ( - 31 ) \pm 11}{2 \cdot 14}

Separate the solutions

x_{1} = \frac{- ( - 31 ) + 11}{2 \cdot 14}, x_{2} = \frac{- ( - 31 ) - 11}{2 \cdot 14}

x = \frac{- ( - 31 ) + 11}{2 \cdot 14} : \frac{3}{2}

x = \frac{- ( - 31 ) - 11}{2 \cdot 14} : \frac{5}{7}

The solutions to the quadratic equation are:

x = \frac{3}{2}, x = \frac{5}{7}

(x - 4)^{2} = 12

21000 = 0.68 \cdot 22 \cdot x \cdot \frac{2.5}{1.4} \cdot (54 - 0.4 x)

\frac{y ^{2}}{2} - 3 = y + 1

\frac{x ^{2} - 6}{2} - \frac{x ^{2} + 4}{4} = 5

2 x^{2} - 18 x = - 28
