Question

$$4 k x ^ { 2 } + 3 k x - 8 = 0 2$$

Solve for k

$k=\frac{8}{x\left(4x+3\right)}$
$x\neq -\frac{3}{4}\text{ and }x\neq 0$

Show Solution

Solve for x (complex solution)

$x=\frac{\sqrt{9k^{2}+128k}}{8k}-\frac{3}{8}$
$x=-\frac{\sqrt{9k^{2}+128k}}{8k}-\frac{3}{8}\text{, }k\neq 0$

Solve for x

$x=\frac{\sqrt{9k^{2}+128k}}{8k}-\frac{3}{8}$
$x=-\frac{\sqrt{9k^{2}+128k}}{8k}-\frac{3}{8}\text{, }k>0\text{ or }k\leq -\frac{128}{9}$
