7 x^{2} - 78 x = 0

x = \frac{78}{7}, x = 0

Solution steps

7 x^{2} - 78 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 78 ) \pm ( - 78 ) ^{2} - 4 \cdot 7 \cdot 0}{2 \cdot 7}

(- 78)^{2} - 4 \cdot 7 \cdot 0 = 78

x_{1, 2} = \frac{- ( - 78 ) \pm 78}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 78 ) + 78}{2 \cdot 7}, x_{2} = \frac{- ( - 78 ) - 78}{2 \cdot 7}

x = \frac{- ( - 78 ) + 78}{2 \cdot 7} : \frac{78}{7}

x = \frac{- ( - 78 ) - 78}{2 \cdot 7} : 0

The solutions to the quadratic equation are:

x = \frac{78}{7}, x = 0

x^{2} - 3 = 9

(2 a - 1) x^{2} + a x + 5 = 0

(\frac{1 + x}{4})^{2} = 9

2 x^{2} - 5 x - 3 = 0

(x + 6)^{2} - 4 (x + 6) - 12 = 0
