Question #N254
What is the value of $x$ if $x^2-4x+3=0$?
A. 1
B. 2
C. 3
D. 4
Correct Answer is: C
We can factor the quadratic equation as $(x-3)(x-1)=0$. Setting each factor equal to zero, we get $x-3=0$ or $x-1=0$. Solving for $x$, we find that $x=3$ or $x=1$. Since choice C is the only option that is a solution to the equation, it is the correct answer.
