x^{2} - 1.7 x + 0.72 = 0

x = \frac{9}{10}, x = \frac{4}{5}

Decimal Notation

x = 0.9, x = 0.8

Solution steps

x^{2} - 1.7 x + 0.72 = 0

Multiply both sides by

100

100 x^{2} - 170 x + 72 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 170 ) \pm ( - 170 ) ^{2} - 4 \cdot 100 \cdot 72}{2 \cdot 100}

(- 170)^{2} - 4 \cdot 100 \cdot 72 = 10

x_{1, 2} = \frac{- ( - 170 ) \pm 10}{2 \cdot 100}

Separate the solutions

x_{1} = \frac{- ( - 170 ) + 10}{2 \cdot 100}, x_{2} = \frac{- ( - 170 ) - 10}{2 \cdot 100}

x = \frac{- ( - 170 ) + 10}{2 \cdot 100} : \frac{9}{10}

x = \frac{- ( - 170 ) - 10}{2 \cdot 100} : \frac{4}{5}

The solutions to the quadratic equation are:

x = \frac{9}{10}, x = \frac{4}{5}

25 x^{2} - 15 x + 2 = 0

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

5 - 2 x = 3 x

(4 - 4 i)^{3}

\frac{8 x ^{5} y ^{4}}{4 x ^{2} y ^{2}}
