25 x^{2} = 20 x - 4

x = \frac{2}{5}

Decimal Notation

x = 0.4

Solution steps

25 x^{2} = 20 x - 4

Move

4

to the left side

25 x^{2} + 4 = 20 x

Move

20 x

to the left side

25 x^{2} + 4 - 20 x = 0

Write in the standard form

a x^{2} + b x + c = 0

25 x^{2} - 20 x + 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 25 \cdot 4}{2 \cdot 25}

(- 20)^{2} - 4 \cdot 25 \cdot 4 = 0

x_{1, 2} = \frac{- ( - 20 ) \pm 0}{2 \cdot 25}

x = \frac{- ( - 20 )}{2 \cdot 25}

\frac{- ( - 20 )}{2 \cdot 25} = \frac{2}{5}

x = \frac{2}{5}

The solution to the quadratic equation is:

x = \frac{2}{5}

- 19 = - 3 - n^{2}

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

3 t^{2} - 6 t = 0

x^{2} + 3 x - 13 = 0

x^{2} = c
