a^{2} - 84 = - 3

a = 9, a = - 9

Solution steps

a^{2} - 84 = - 3

Move

84

to the right side

a^{2} = 81

For

x^{2} = f (a)

the solutions are

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

a = 81, a = - 81

81 = 9

- 81 = - 9

a = 9, a = - 9

x^{2} + (x + 1)^{2} = 61

- 6 x < 30

2 4^{\frac{3}{2}}

12 y^{2} - 58 y - 70

w^{2} + 5 w - 86 = 0
