24=x^2-4x+3 Rewrite the equation by completing the square.

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

24=x2−4x+3

Step 1: Subtract x^2-4x+3 from both sides.

24−(x2−4x+3)=x2−4x+3−(x2−4x+3)

−x2+4x+21=0

Step 2: Factor left side of equation.

(−x−3)(x−7)=0

Step 3: Set factors equal to 0.

−x−3=0 or x−7=0

x=−3 or x=7

x=−3 or x=7
