c^{2} - 9 = 0

c = 3, c = - 3

Solution steps

c^{2} - 9 = 0

Move

9

to the right side

c^{2} = 9

For

x^{2} = f (a)

the solutions are

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

c = 9, c = - 9

9 = 3

- 9 = - 3

c = 3, c = - 3

\frac{x ^{2}}{2} + \frac{x}{2} = 10

- 3 x = 5 x^{2}

9 x^{2} = - 6 x - 1

- 2 x^{2} + 9 x + 3 = 0

2 x^{2} + 6 x + 7
