- 14 = r^{2} - 23

r = 3, r = - 3

Solution steps

- 14 = r^{2} - 23

Switch sides

r^{2} - 23 = - 14

Move

23

to the right side

r^{2} = 9

For

x^{2} = f (a)

the solutions are

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

r = 9, r = - 9

9 = 3

- 9 = - 3

r = 3, r = - 3

15 x^{2} - 11 x + 2 = 0

5 x^{2} + 2 x + 4 = 0

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

x^{2} - 11 x = 42

- \frac{1}{2} n^{2} + 18 = 0
