Answer:
There are no solutions.
Step-by-step explanation:
im assuming that the equation is x^2+20=2x, but if not, x=10.
quadratic formula is
(-b+-√(b^2-4ac))/2a, and a=1, b=-2, and c=20. plug these values in and you will find that you are asked to square root a negative number. There are no solutions.
