Answer:

x=-2 or x= -8.

Step-by-step explanation:

We have the equation

$x^2+10x+16=0$

To factor the polynomial we search two numbers that multiplied are 16 and added are 10. In this case, 8 and 2:

(x+2)(x+8)=0.

As we have a product equal to 0, one of the factors needs to be 0. Then,

x+2 = 0 or x+8 = 0

x = -2 or x = -8.

I’m confused on this

$\huge\boxed{x=25}$

The mistake is in Step 1. The solver should have also squared $9$ when squaring the other side of the equation.

<h3>Correctly solving</h3>

$\begin{aligned}\sqrt{3x+6}&=9\\(\sqrt{3x+6})^2&=9^2\\3x+6&=81\\3x+6-6&=81-6\\3x&=75\\\frac{3x}{3}&=\frac{75}{3}\\x&=25\end{aligned}$
