Solve: -5x - 6 = -6x²

You missed the fact that one of the x's is squared Anonymous!

Add 6x² to both sides of the equation:

6x² - 5x - 6 = 0

This can be factored as

(3x + 2)(2x - 3) = 0

so x = -2/3  and x = 3/2

.

$${\mathtt{\,-\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{6}} = {\mathtt{\,-\,}}\left({\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{x}}\right) \Rightarrow {\mathtt{x}} = {\mathtt{6}}$$ hope this helps.
