5 x^{2} - 30 x - 7 = - 7

x = 6, x = 0

Solution steps

5 x^{2} - 30 x - 7 = - 7

Move

7

to the left side

5 x^{2} - 30 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 5 \cdot 0}{2 \cdot 5}

(- 30)^{2} - 4 \cdot 5 \cdot 0 = 30

x_{1, 2} = \frac{- ( - 30 ) \pm 30}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 30 ) + 30}{2 \cdot 5}, x_{2} = \frac{- ( - 30 ) - 30}{2 \cdot 5}

x = \frac{- ( - 30 ) + 30}{2 \cdot 5} : 6

x = \frac{- ( - 30 ) - 30}{2 \cdot 5} : 0

The solutions to the quadratic equation are:

x = 6, x = 0

x^{2} + 2 = 83

x^{2} + 2 = 18

(3 x - 4)^{2} - 6 = (2 x - 5)^{2}

x, 6 x y - 3 x^{2} = 0

8 x^{2} - 15 x + 10 = 0
