Question

solve x^2-4x+3=0 using quadratic formula

Answer 1

identify your a, b, and c in your equation: ax^2 + bx + c = 0 then plug it into the QF

Answer 2

what is the quadratic equation??

Answer 3

do not need jut factoriz it
- check two numbers what assumed will add you -4 and theyr product equal 3

Answer 4

just factoriz it

Answer 5

can you get these ?

Answer 6

im lost....

Answer 7

hence is more easy

Answer 8

but with quadratic formula
so do you know the discriminant

Answer 9

well the quadratic formula is
-b +/- *sqrt (b^2 - 4(a)(c)
------------------------
2a
So we plug it in as said before,
-(-4) +/- *sqrt ((-4)^2 - 4(1)(3)
------------------------
2(1)
4 +/- *sqrt (16 - 12)
-------------------
2
4 +/- *sqrt (4)
--------------
2
4 +/- 2
-------
2
4 + 2 6
------ = -- = 3
2 2
4 - 2 2
------ = -- = 1
2 2
so the answers are x = 1 and x = 3; if anything you can enter them in the original problem to check your answer

Answer 10

I attached a picture of the quadratic equation.
In your problem, \[x^2-4x+3=0\]
a = 1, b = -4, c = 3.
So just plug in those values, and you should be able to solve your problem.
