Answer:
6 is not a solution to the given equation.
Step-by-step explanation:
We are given the equation [tex]x^2-4=5x[/tex]
We need to know whether or not x=6 is a solution. This means that we should substitute in 6 for each instance of x. Then, if both sides of the equation are equal, then 6 is a solution to the equation.
[tex]x^2-4=5x\\\\(6)^2-4=5(6)\\\\36-4=30\\\\32=30[/tex]
As 32 ≠ 30, 6 is not a solution to the given equation.
