Answer:

x=4 and x= - 5

Step-by-step explanation:

In order to solve this we should re-arrange the equation:

[tex](x-4)(x+5)=\frac{0}{3}[/tex]

This is equal to:

[tex](x-4)(x+5)=0[/tex]

Then we can seperate this into:

[tex](x-4)=0\\(x+5)=0[/tex]

So solving for x in both cases we get

[tex]x-4=0 \\x=4\\And\\x+5=0\\x=-5\\[/tex]
