to solve this quadratic equation there's
a number of ways to do that I'm gonna
solve this by extracting roots so the
first step is to isolate the square
adding 75 gives us 3x squared equals 75
then dividing by 3 we'll be left with x
squared equals 25 okay once you have the
square by itself you can then take the
square root of both sides don't forget
whenever you take the square root you
have to include the plus or minus so
that you don't lose the negative
solution that leaves us with x equals
plus or minus 5 so here we got two
solutions okay so the solutions here are
negative 5 and positive 5 you can
actually plug those into the original
see if they work as a check
