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

x = \frac{3}{8} - i \frac{3 15}{8}, x = \frac{3}{8} + i \frac{3 15}{8}

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 ( - 4 ) ( - 9 )}{2 ( - 4 )}

Simplify

3^{2} - 4 (- 4) (- 9) : 315 i

x_{1, 2} = \frac{- 3 \pm 3 15 i}{2 ( - 4 )}

Separate the solutions

x_{1} = \frac{- 3 + 3 15 i}{2 ( - 4 )}, x_{2} = \frac{- 3 - 3 15 i}{2 ( - 4 )}

x = \frac{- 3 + 3 15 i}{2 ( - 4 )} : \frac{3}{8} - i \frac{3 15}{8}

x = \frac{- 3 - 3 15 i}{2 ( - 4 )} : \frac{3}{8} + i \frac{3 15}{8}

The solutions to the quadratic equation are:

x = \frac{3}{8} - i \frac{3 15}{8}, x = \frac{3}{8} + i \frac{3 15}{8}

m, F = g \frac{mm}{d ^{2}}

r^{2} + 20 r - 2 = 0

x^{2} - 4 x - 3 = 0

7^{2} = b^{2} + b^{2}

(x - 9)^{2} + 18 = 0
