Question

Can someone help me with real solutions please?

Answer 1

Got a question, or naw?

Answer 2

0=5x^2+2x-12 can u do it in steps?

Answer 3

how many will be the discriminant ?

Answer 4

hope you know these categories of roots in function of discriminant - yes ?

Answer 5

when D < 0
D = 0
D > 0

- do you know ?

Answer 6

5x^2 +2x -12 = 0

D = b^2 -4ac = 2^2 -(4*5*(-12)) = ?

Answer 7

@Casadie1004 please collaborate

Answer 8

so than will get the discriminant greater than zero so this mean that the quadratic has two real different roots

Answer 9

and than the discriminant is equal zero so than the quadratic has two real but equal roots
- and than the discriminant is less than zero so than the quadratic have not real roots
