4 x^{2} - 72 = 0

x = 32, x = - 32

Decimal Notation

x = 4.24264 \dots, x = - 4.24264 \dots

Solution steps

4 x^{2} - 72 = 0

Move

72

to the right side

4 x^{2} = 72

Divide both sides by

4

x^{2} = 18

For

x^{2} = f (a)

the solutions are

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

x = 18, x = - 18

18 = 32

- 18 = - 32

x = 32, x = - 32

(- \frac{1}{3})^{2} + y^{2} = 1

- 4.9 t^{2} + 73.92 = \frac{1}{2} \cdot 73.92

z^{2} + 6 z + 10

2 v^{2} + 5 v = 7

2 x^{2} - 12 = - 15
