to solve this quadratic equation I
notice the square is already isolated so
let's extract the roots to do that all
we have to do is take the square root of
both sides but the thing is when you do
that don't forget the plus or minus
again the left side we're left with X
plus 3 equals plus or minus now the
square root of twenty-seven i'm going to
rewrite that as nine times three okay
simplifying we have X plus three equals
plus or minus three your screw-up square
root of three square root of nine is
three okay and then for my final step
here let's go ahead and subtract three
and then I can solve for x here x equals
negative 3 plus or minus 3 root 3 okay
so we did get two solutions here the
first solution here is negative 3 minus
3 root 3 and the second one is negative
3 plus 3 square root of three
