x^{2} - 61 = 20

x = 9, x = - 9

Solution steps

x^{2} - 61 = 20

Move

61

to the right side

x^{2} = 81

For

x^{2} = f (a)

the solutions are

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

x = 81, x = - 81

81 = 9

- 81 = - 9

x = 9, x = - 9

\frac{4 ( c ) ^{3}}{3 c ^{7}}

2 (4 x - 6) = 6 x - 4

4 c^{2} - 15 c + 9

∣ 2 x - 2 ∣ < 6

\frac{4}{9} \cdot \frac{1}{4}
