Question

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

Answer 1

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

Answer 2

2/10 +- sqrt(4-(4)(5)(1))/10

2/10 +- sqrt(4 - 20)/10

you want real roots or imaginary?

Answer 3

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

Answer 4

1) real, rational, unequal
2) real, rational, equal
3) real, irrational, unequal
4) imaginary

also i don't understand the work you did

Answer 5

nicolenova,

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

Answer 6

delta= b^2 - 4ac

Answer 7

ooohhhh i messed up the equation! thanks!!

Answer 8
