Answer:
1 and 3
Step-by-step explanation:
So they asked you to use the quadratic formula. The quadratic formula is x=-b+/-sqrt b^2-4ac/2a.
So your equation is x^2-4x+3.
x^2 is a. -4 is b. and 3 is c.
x=4+/-sqrt (-4)^2-4(1)(3)/2(1).
This will equal 4+/-sqrt16-12/2
It will simplify to 4+/-2/2.
No you have two equations 4+2/2 and 4-2/2.
4+2/2=3.
4-2/2=1.
Your answers are 1 and 3.
