F(x)=6x^2+10x−1 How many distinct real number zeros does f have?
Nonamiya [84]

Answer:

Here, D>0, hence the quadratic equation has two distinct real roots.

Step-by-step explanation:

Given quadratic equation is 6x^{2} +10x-1.

Let, the quadratic equation is ax^{2} +bx+c    [where, a,b,c are the constants]

The Discriminant (D)=b^{2}-4ac

Case 1:   b^{2}-4ac>0, if the discriminant is greater than 0, it means the quadratic equation has two real distinct roots.

Case 2: b^{2}-4ac, if the discriminant is less than 0, it means the quadratic equation has no real roots.

Case 3: b^{2}-4ac=0, if the discriminants is equal to 0, it means the quadratic equation has two real identical roots.

Now,

      we have 6x^{2} +10x-1, where a=6,b=10,\ and\  c=-1

∴D=b^{2}-4ac

     =(10)^{2}-(4\times 6\times\ -1)

     =100+24

     = 124

Here, D>0, hence the quadratic equation has two distinct real roots.
