x^{2} + 3 x - 72 = 0

x = \frac{3 33 - 3}{2}, x = \frac{- 3 33 - 3}{2}

Decimal Notation

x = 7.11684 \dots, x = - 10.11684 \dots

Solution steps

x^{2} + 3 x - 72 = 0

Move

72

to the right side

x^{2} + 3 x = 72

Rewrite in the form

(x + a)^{2} = b

(x + \frac{3}{2})^{2} = \frac{297}{4}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{3}{2} = \frac{297}{4} : x = \frac{3 33 - 3}{2}

Solve

x + \frac{3}{2} = - \frac{297}{4} : x = \frac{- 3 33 - 3}{2}

The solutions to the quadratic equation are:

x = \frac{3 33 - 3}{2}, x = \frac{- 3 33 - 3}{2}

- 66.18 \cdot X^{2} - 2.46 \cdot X - 0.027 = - 12.5

a^{2} + 14 a + 49 = 0

12 x^{2} - 4 x - 1 = 0

x^{2} - 15 x - 56 = 0

y, x^{3} + 3 y^{2} z - x y z^{3} = 0
