What is the discriminant of the quadratic equation 9x^2– 8x – 2 = 0?

Step-by-step explanation:

The quadratic formula helps us find the roots of a quadratic equation. The equation is:

where

The discriminant is just the part under the square root. This helps tell us if there are two, one, or zero real solutions.

The discriminant is:

We are given the quadratic:

Therefore, a is 9, b is -8, and c is -2.

Solve the exponent.

Multiply 4, 9, and -2.

The discriminant is 136. Since it is a non-zero, positive number, this quadratic has 2 real solutions/zeroes/roots.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
