5 a^{2} - 100 = 0

a = 25, a = - 25

Decimal Notation

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

Solution steps

5 a^{2} - 100 = 0

Move

100

to the right side

5 a^{2} = 100

Divide both sides by

5

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

2 x^{2} + 192 = 40 x

X^{2} = 3 X + 4

y^{2} + 2 y + 10 = 0

- 5 = - 0.0156 x^{2} + 0.1123 x - 3.25

\frac{( x ^{2} + 3 )}{2} = 14
