Question 995565
3x²-13x+4=0
x²-13x/3+4/3=0
x²-13x/3=-4/3
take the half of 13/3,square it,then add it to bothside
From the above,half of 13/3 is 26/3 then it's square is 676/9,Then add 676/9 in bothside of the equation,
x²-13x/3+676/9=676/9-4/3
(x-26/3)²=(676-12)/9
(x-26/3)²=664/9
solve it from here!!!
