a^{2} - 120 = 100

a = 255, a = - 255

Decimal Notation

a = 14.83239 \dots, a = - 14.83239 \dots

Solution steps

a^{2} - 120 = 100

Move

120

to the right side

a^{2} = 220

For

x^{2} = f (a)

the solutions are

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

a = 220, a = - 220

220 = 255

- 220 = - 255

a = 255, a = - 255

7 x^{2} + x - 5 = 0

x, 5 x^{2} - 4 x y + y^{2} = 0

9 x^{2} + 4 x - 8 = 0

15 + x (x + 2 x) = 10

2 r^{2} - r + 1 = 0
