The given expression is
[tex]x^2-8x-33=0[/tex]
To solve this equation, we have to look for two numbers which product is 33, and which difference is 8. Those numbers are 11 and 3.
[tex]x^2-8x-33=(x-11)(x+3)[/tex]
Then, we isolate the variables.
[tex]\begin{gathered} x=11 \\ x=-3 \end{gathered}[/tex]
Hence, the right answers are x = 11 and x = -3.
