x^{2} + 3 \cdot (- 28) = 0

x = 221, x = - 221

Decimal Notation

x = 9.16515 \dots, x = - 9.16515 \dots

Solution steps

x^{2} + 3 (- 28) = 0

Expand

x^{2} + 3 (- 28) : x^{2} - 84

x^{2} - 84 = 0

Move

84

to the right side

x^{2} = 84

For

x^{2} = f (a)

the solutions are

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

x = 84, x = - 84

84 = 221

- 84 = - 221

x = 221, x = - 221

y, e^{y} = x^{2}

x + 12 x^{2} = 6

(x) (x) = 2 x

9 x^{2} - 2 x - 3 = 0

x, x^{2} + 4 y^{2} = 4 a y
