3 - 15 - 2 x - x^{2} = 0

x = - 1 - 7, x = 7 - 1

Decimal Notation

x = - 3.64575 \dots, x = 1.64575 \dots

Solution steps

3 - 15 - 2 x - x^{2} = 0

Move

3

to the right side

- 15 - 2 x - x^{2} = - 3

Square both sides:

15 - 2 x - x^{2} = 9

15 - 2 x - x^{2} = 9

Solve

15 - 2 x - x^{2} = 9 : x = - 1 - 7, x = 7 - 1

x = - 1 - 7, x = 7 - 1

Verify Solutions:

x = - 1 - 7

True

, x = 7 - 1

True

The solutions are

x = - 1 - 7, x = 7 - 1

x^{2} + 48 x = 10

(x - 2)^{\frac{1}{3}} = - 5

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

4 x + 5 - 2 x + 2 + 1 = 0
