Question

Who knows about discriminant in algebra 2?

Answer 1

what do u want to know?

Answer 2

The discriminant is the expression b2 – 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has.


If you get a positive number, the quadratic will have two unique solutions. If you get 0, the quadratic will have exactly one solution, a double root. If you get a negative number, the quadratic will have no real solutions, just two imaginary ones.

Answer 3

Could you help distinguish a negative discriminant on a graph?

Answer 4

you got all the info u need i what i posted

Answer 5

Thanks

Answer 6

graph 2 would be no solution meaning - number

Answer 7

Really?

Answer 8

if the graph does not have x intercepts, it means it has no real solution. so, wich of those does not even touch the x axis ?

Answer 9

only the second one

Answer 10

Oh I see

Answer 11

uhh, i guess thtas a thanks !

Answer 12

Yes, yes:) Thank you so very much!! @timo86m @Luis_Rivera

Answer 13

kk

Answer 14

also think about this way.

ax^2+bx+c=0

roots are also known as zero. the zero is the x axist. ANd it never intercepts. Therefore no zeros, and no solution.
