roots

x^{2} + 2 x + 15

x = - 1 + 14 i, x = - 1 - 14 i

Solution steps

x^{2} + 2 x + 15

The roots are the intercepts with the x-axis

(y = 0)

x^{2} + 2 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

Simplify

2^{2} - 4 \cdot 1 \cdot 15 : 214 i

x_{1, 2} = \frac{- 2 \pm 2 14 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 2 + 2 14 i}{2 \cdot 1}, x_{2} = \frac{- 2 - 2 14 i}{2 \cdot 1}

x = \frac{- 2 + 2 14 i}{2 \cdot 1} : - 1 + 14 i

x = \frac{- 2 - 2 14 i}{2 \cdot 1} : - 1 - 14 i

The solutions to the quadratic equation are:

x = - 1 + 14 i, x = - 1 - 14 i

4.5 \times 1 0^{- 4} = \frac{x ^{2}}{0.03}

x^{2} - 15 = - 271

5 x^{2} + 18 x + 22 = 0

x^{2} + 12 x + 27 = 0

5 x^{2} - 8 x - 7 = 0
