Factoring Inequalities,<br><br> Please help as I do not know how to progress after this.

Rainbow [258]

The factored inequality is $x^2-3x+6\geq 0$

<h3>Factoring Inequalities</h3>

The given inequality is:

$-x^2+3x-6\leq 0$

This can be further simplified as:

$-(x^2-3x+6)\leq 0$

The inequality can be re-written as:

$x^2-3x+6\geq 0$

Since the question does not state that we should solve the inequality, the simplest we can get after factoring is $x^2-3x+6\geq 0$
