Solve the equation using the quadratic formula. x^2-4x+3=0

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

x2-4x+3=0

Step 1: Factor left side of equation.

(x-1) (x-3) = 0

Step 2: Set factors equal to 0.

x-1=0 or x-3=0

For this one add one on both sides

x-1+1=0+1 x=1

For this one add 3 on both sides

x-3+3=0+3. x=3

x=1 or x=3
