9 a^{2} - 40 = 0

a = \frac{2 10}{3}, a = - \frac{2 10}{3}

Solution steps

9 a^{2} - 40 = 0

Move

40

to the right side

9 a^{2} = 40

Divide both sides by

9

a^{2} = \frac{40}{9}

For

x^{2} = f (a)

the solutions are

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

a = \frac{40}{9}, a = - \frac{40}{9}

\frac{40}{9} = \frac{2 10}{3}

- \frac{40}{9} = - \frac{2 10}{3}

a = \frac{2 10}{3}, a = - \frac{2 10}{3}

5 x^{2} - 38 x - 16 = 0

n - 5 n + 12 = 3 n^{2}

x^{2} + 8 x - 9 = 0

- 6 x^{2} + 7 x = 7 x - 4

- z^{2} - 7 z - 4 = - 2 z^{2}
