Answer 1

Answer:

x=1,2

Step-by-step explanation:

a quadratic can be written in the form

ax^2 + bx +c = 0

x²-3x+2=0

a =1    b = -3   c =2

The quadratic equation is

x = -b ± sqrt( b^2 -4ac)

        --------------------

             2a

  =  3 ± sqrt( (-3)^2 -4(1)(2))

        --------------------

             2(1)

         3 ± sqrt( 1)

        --------------------

             2

(3+1)/2    and  (3-1)/2

4/2         and 2/2

2 and 1
