How can I solve this equation 5x^2-2x-6=-2x^2+9x

wel

Add 2x^2 to both sides
7x^2-2x-6=9x

Subtract 9x from both sides
7x^2-11x-6=0

Factor by using slip and slide
x^2-11x-42
(x-14)(x+3)
(x-14/7)(x+3/7)
(x-2)(7x+3)

Then use the Zero Product Property to find roots
x-2=0
x=2

7x+3=0
7x=-3
x=-3/7

Final answer: x=-3/7, x=2

Answer:

${ \tt{ \frac{1}{x} + \frac{1}{3} < \frac{1}{5} }} \\ \\ { \tt{ \frac{1}{x} > - \frac{2}{15} }} \\ \\ { \tt{x > - \frac{15}{2} }} \\ \\ { \bf{ - \frac{15}{2} < x < 0 }}$
