- \frac{1}{5} x^{2} + 20 = 0

x = 10, x = - 10

Solution steps

- \frac{1}{5} x^{2} + 20 = 0

Move

20

to the right side

- \frac{1}{5} x^{2} = - 20

Multiply both sides by

- 5

x^{2} = 100

For

x^{2} = f (a)

the solutions are

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

x = 100, x = - 100

100 = 10

- 100 = - 10

x = 10, x = - 10

8 x^{2} - 5 x - 3 = 0

x + 1 = 10 x^{2}

a, (a - b)^{2} = 0

2 c^{2} + 14 c + 10 = - 3

r^{2} - 10 + 25 = 1
