x^{2} - 6.4 x = - 1.24

x = \frac{31}{5}, x = \frac{1}{5}

Decimal Notation

x = 6.2, x = 0.2

Solution steps

x^{2} - 6.4 x = - 1.24

Multiply both sides by

100

100 x^{2} - 640 x = - 124

Move

124

to the left side

100 x^{2} - 640 x + 124 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 640 ) \pm ( - 640 ) ^{2} - 4 \cdot 100 \cdot 124}{2 \cdot 100}

(- 640)^{2} - 4 \cdot 100 \cdot 124 = 600

x_{1, 2} = \frac{- ( - 640 ) \pm 600}{2 \cdot 100}

Separate the solutions

x_{1} = \frac{- ( - 640 ) + 600}{2 \cdot 100}, x_{2} = \frac{- ( - 640 ) - 600}{2 \cdot 100}

x = \frac{- ( - 640 ) + 600}{2 \cdot 100} : \frac{31}{5}

x = \frac{- ( - 640 ) - 600}{2 \cdot 100} : \frac{1}{5}

The solutions to the quadratic equation are:

x = \frac{31}{5}, x = \frac{1}{5}

x, z = x^{2} + 2 y^{2}

3 r^{2} + 6 r + 1 = 0

y^{2} + 2 y - 80 = 0

3 x^{2} - 4 x + 1 = 2 x^{2} + 3 x - 4

x^{2} - 1 = 29
