x^{2} - 1.6 x + 0.64 = 0

x = \frac{4}{5}

Decimal Notation

x = 0.8

Solution steps

x^{2} - 1.6 x + 0.64 = 0

Multiply both sides by

100

100 x^{2} - 160 x + 64 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 160 ) \pm ( - 160 ) ^{2} - 4 \cdot 100 \cdot 64}{2 \cdot 100}

(- 160)^{2} - 4 \cdot 100 \cdot 64 = 0

x_{1, 2} = \frac{- ( - 160 ) \pm 0}{2 \cdot 100}

x = \frac{- ( - 160 )}{2 \cdot 100}

\frac{- ( - 160 )}{2 \cdot 100} = \frac{4}{5}

x = \frac{4}{5}

The solution to the quadratic equation is:

x = \frac{4}{5}

- 7 x - 90 + 5 x^{2} = 0

x^{2} = 9 (x - 2)

a^{2} - 11 a + 18 = 0

x, y^{4} (x) - 8 y^{2} (x) + 16 y = x^{2}

3 x (x + 2) (2 x - 3) + 4 = 2 x (3 x - 2) (x + 2) + 3
