the roots of the equation 5x^2 -2x +1 = 0 are...

OpenStudy (amistre64):

5(1) = 5 .... 1,5; nothing there..... gotta quad formulate it

OpenStudy (amistre64):

2/10 +- sqrt(4-(4)(5)(1))/10 2/10 +- sqrt(4 - 20)/10 you want real roots or imaginary?

OpenStudy (amistre64):

it dont touch the x axis, so it aint got no roots :) not in this universe at least

OpenStudy (anonymous):

1) real, rational, unequal 2) real, rational, equal 3) real, irrational, unequal 4) imaginary also i don't understand the work you did

OpenStudy (anonymous):

nicolenova, if discriminant delta is < 0 the roots will be imaginary! (4)

OpenStudy (anonymous):

delta= b^2 - 4ac
