<PRE><B>Question 899871</B>
Please may solve this problem to me graphically x^2-3x+7
----------------
y = x^2 - 3x + 7
------
{{{graph(400,400,-10,10,-10,10,x^2 - 3x + 7)}}}
-----
Since the graph does not cross the x-axis, there are no Real Number solutions.
-----
Using the Quadratic Formula you get:
x = [3 +- sqrt(9-4*1*7)]/2
x = [3 +- sqrt(-19)]/2
x = (3+-i*sqrt(19))/2
--------------------------

Stan H.
