Do 3x^2-7x+2=0
verify that the sum of the solution is -b/a and verify that the product of the solution is c/a
from the equation:
sum of roots = 7/3
product of roots = 2/3
3x^2-7x+2=0
(x-2)(3x-1) = 0
x = 2 or x = 1/3
sum of roots = 2 + 1/3 = 7/3 , that checks
product of roots = 2(1/3) = 2/3, and that checks
