Question

help math is bad........

Answer 1

Answer:$x=5$$or$$x=-5$

Step-by-step explanation:

To solve the inequality, $-x^{2}+25\leq 0$ (Ignore the line under the less than sign), we have to separate, $x$, and make it alone. So let's rearrange to solve for

$-x^{2}+25\leq 0$

$-x^{2} \leq -25$

$x^{2} \leq 25$

$\sqrt{x^{2} } \leq \sqrt{25}$

$x=5,-5$

As you can see, $x$ can be either 5 or -5 because when you square root a number, there is a positive and a negative number. Mostly, teachers tends to ignore the negative number but in math problems like these, the negative number is important.

The final answer is the second multiple choice:

$x=5$$or$$x=-5$
