- x^{2} - 12 = - 87

x = 53, x = - 53

Decimal Notation

x = 8.66025 \dots, x = - 8.66025 \dots

Solution steps

- x^{2} - 12 = - 87

Move

12

to the right side

- x^{2} = - 75

Divide both sides by

- 1

x^{2} = 75

For

x^{2} = f (a)

the solutions are

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

x = 75, x = - 75

75 = 53

- 75 = - 53

x = 53, x = - 53

4 x^{2} + 20 x + 29 = 0

4 x^{2} + 196 = 0

(x - 5)^{2} + 49 = 0

e^{3} (x^{2} + 1) = x^{2}

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