x \cdot 2 x = 72

x = 6, x = - 6

Solution steps

x \cdot 2 x = 72

Simplify

2 x^{2} = 72

Divide both sides by

2

\frac{2 x ^{2}}{2} = \frac{72}{2}

x^{2} = 36

For

x^{2} = f (a)

the solutions are

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

x = 36, x = - 36

36 = 6

- 36 = - 6

x = 6, x = - 6

x^{2} + 2 x - 39

2 x - 1 - x + 2 = x^{2} - 8 - 2 x - 1

6 q^{2} = 144

5 x^{2} - 50 x + 95 = 0

x^{2} - 5 x - 30 = 0
