x^{2} - 1.6 x + 0.63 = 0

x = \frac{9}{10}, x = \frac{7}{10}

Decimal Notation

x = 0.9, x = 0.7

Solution steps

x^{2} - 1.6 x + 0.63 = 0

Multiply both sides by

100

100 x^{2} - 160 x + 63 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 160 ) \pm ( - 160 ) ^{2} - 4 \cdot 100 \cdot 63}{2 \cdot 100}

(- 160)^{2} - 4 \cdot 100 \cdot 63 = 20

x_{1, 2} = \frac{- ( - 160 ) \pm 20}{2 \cdot 100}

Separate the solutions

x_{1} = \frac{- ( - 160 ) + 20}{2 \cdot 100}, x_{2} = \frac{- ( - 160 ) - 20}{2 \cdot 100}

x = \frac{- ( - 160 ) + 20}{2 \cdot 100} : \frac{9}{10}

x = \frac{- ( - 160 ) - 20}{2 \cdot 100} : \frac{7}{10}

The solutions to the quadratic equation are:

x = \frac{9}{10}, x = \frac{7}{10}

\frac{4 ( t - 1.4 ) ^{2}}{2} = \frac{87 t}{3.6}

2 x^{2} + 5 x + 2

x, x y + 2 x + 3 x^{2} = 4

\frac{4}{3} x^{2} = \frac{2}{3} x^{2} + 6

x^{2} - 2 x - 4
