7 x^{2} - 20 x = 3

x = 3, x = - \frac{1}{7}

Decimal Notation

x = 3, x = - 0.14285 \dots

Solution steps

7 x^{2} - 20 x = 3

Move

3

to the left side

7 x^{2} - 20 x - 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 7 ( - 3 )}{2 \cdot 7}

(- 20)^{2} - 4 \cdot 7 (- 3) = 22

x_{1, 2} = \frac{- ( - 20 ) \pm 22}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 22}{2 \cdot 7}, x_{2} = \frac{- ( - 20 ) - 22}{2 \cdot 7}

x = \frac{- ( - 20 ) + 22}{2 \cdot 7} : 3

x = \frac{- ( - 20 ) - 22}{2 \cdot 7} : - \frac{1}{7}

The solutions to the quadratic equation are:

x = 3, x = - \frac{1}{7}

x, 3 x^{2} - y^{2} - 12 x + 2 y + 11 = 0

x \cdot (20 x - 21) = 27

D = (2 a - 3)^{2} - (a + 5) (a - 5) + \frac{6 a + 68}{2}

15 z^{2} + 6 z - 8 = 4 z

- 0.03 q^{2} + 975 = 35 q + 263
