r^{2} - 144 = 0

r = 12, r = - 12

Solution steps

r^{2} - 144 = 0

Move

144

to the right side

r^{2} = 144

For

x^{2} = f (a)

the solutions are

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

r = 144, r = - 144

144 = 12

- 144 = - 12

r = 12, r = - 12

4 x^{2} + 26 x + 30 = 0

- 5 x^{2} + 10 = 0

15 x^{2} = 540

9 x^{2} + 18 x - 17 = 0

\frac{17}{10} x^{2} + 3 x + 5 = 0
