4 (x^{2} - 8) = 84

x = 29, x = - 29

Decimal Notation

x = 5.38516 \dots, x = - 5.38516 \dots

Solution steps

4 (x^{2} - 8) = 84

Divide both sides by

4

x^{2} - 8 = 21

Move

8

to the right side

x^{2} = 29

For

x^{2} = f (a)

the solutions are

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

x = 29, x = - 29

\frac{1}{( 3 i ) ^{3}}

1 - 0.0062

3 m^{2} - 14 m + 15

\frac{4 ( 5 + x )}{3} = 2 x + 2

2 x^{2} + 9 x + 4 \geq 0
