2 x^{2} + 2 = 40

x = 19, x = - 19

Solution steps

2 x^{2} + 2 = 40

Move

2

to the right side

2 x^{2} = 38

Divide both sides by

2

x^{2} = 19

For

x^{2} = f (a)

the solutions are

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

x = 19, x = - 19

- 5 x \leq 25

(- 2)^{7}

- 19 v = - 19

\frac{- 5 + 3 i}{i}

7 + \frac{7}{2}
