(2 x - 5)^{2} = 81

x = 7, x = - 2

Solution steps

(2 x - 5)^{2} = 81

For

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

the solutions are

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

Solve

2 x - 5 = 81 : x = 7

Solve

2 x - 5 = - 81 : x = - 2

The solutions to the quadratic equation are:

x = 7, x = - 2

4^{x} > 2^{x}

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

7 x^{2} + 7 x + 7

(x^{- 1} + y^{- 1})^{- 2}

(5)^{- 1}
