(5 x - 7)^{2} - 1 = 8

x = 2, x = \frac{4}{5}

Decimal Notation

x = 2, x = 0.8

Solution steps

(5 x - 7)^{2} - 1 = 8

Move

1

to the right side

(5 x - 7)^{2} = 9

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

5 x - 7 = 9 : x = 2

Solve

5 x - 7 = - 9 : x = \frac{4}{5}

The solutions to the quadratic equation are:

x = 2, x = \frac{4}{5}

5 x^{2} - 3125 = 0

6 x^{2} + 4 x + 1 = 0

- 3 y + 28 = y^{2}

x^{2} - 50 x + 600 = 0

2 x^{2} + 28 x + 96 = 0
