What is the value of the discriminant for the quadratic equation 0 = 2x2 + x – 3?

discriminant = b2 – 4ac

a. –25
b. –23
c. 25
d. 26

 Option 'c' is correct.

Step-by-step explanation:

Since we have given that

The quadratic equation as follows:

We need to find the value of discriminant for the above quadratic equation:

As we know the formula for "Discriminant":

Here, a = 2

b= 1

c= - 3

So,

Hence, The value of discriminant would be 25.

Therefore, Option 'c' is correct.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
