20 - t^{2} = 0

t = 25, t = - 25

Decimal Notation

t = 4.47213 \dots, t = - 4.47213 \dots

Solution steps

20 - t^{2} = 0

Move

20

to the right side

- t^{2} = - 20

Divide both sides by

- 1

t^{2} = 20

For

x^{2} = f (a)

the solutions are

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

t = 20, t = - 20

20 = 25

- 20 = - 25

t = 25, t = - 25

x^{2} + x - 12 = 0

x^{2} = 8 x - 15

x^{2} = 8 x + 8

- w^{2} - 3 w - 2 = - 5 w^{2}

n^{2} - 6 n - 7 = 0
