5 a^{2} - 45 = 0

a = 3, a = - 3

Solution steps

5 a^{2} - 45 = 0

Move

45

to the right side

5 a^{2} = 45

Divide both sides by

5

a^{2} = 9

For

x^{2} = f (a)

the solutions are

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

a = 9, a = - 9

9 = 3

- 9 = - 3

a = 3, a = - 3

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

- x^{2} + 10 x = 24

x^{2} - 3 x + 2 = 6

x^{2} - 18 x + 81 = 16

9 r (r - 2) = r^{2} + 5
