Answer:

no solution

Explanation:

Let's solve your equation step-by-step.

x2−3x+41=0

Step 1: Subtract 41 from both sides.

x2−3x+41−41=0−41

x2−3x=−41

Step 2: The coefficient of -3x is -3. Let b=-3.

Then we need to add (b/2)^2=9/4 to both sides to complete the square.

Add 9/4 to both sides.

x2−3x+
