a^{2} - 20 = 0

a = 25, a = - 25

Decimal Notation

a = 4.47213 \dots, a = - 4.47213 \dots

Solution steps

a^{2} - 20 = 0

Move

20

to the right side

a^{2} = 20

For

x^{2} = f (a)

the solutions are

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

a = 20, a = - 20

20 = 25

- 20 = - 25

a = 25, a = - 25

m^{2} + 96 = 0

x^{2} + 12 x - 48 = 0

3 m^{2} - 17 m - 28 = 0

5 r^{2} - 44 r + 120 = - 30 + 11 r

x^{2} - 10 x + 3
