\frac{5 x ^{2}}{6} - \frac{x ^{2}}{3} = 72

x = 12, x = - 12

Solution steps

\frac{5 x ^{2}}{6} - \frac{x ^{2}}{3} = 72

Multiply by LCM

3 x^{2} = 432

Divide both sides by

3

x^{2} = 144

For

x^{2} = f (a)

the solutions are

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

x = 144, x = - 144

144 = 12

- 144 = - 12

x = 12, x = - 12

5 x^{2} - 21 x = 0

72 x^{2} + 12 x - 24 = 0

3 x^{2} - \frac{44}{3} x + \frac{35}{3} = \frac{1}{3} (x - 1)

12 y^{2} - 17 y - 5 = 0

x^{2} + 8 x + 15 = - 4
