Question 1
State the value of the discriminant for y = x2 – 8x + 10.
a) 10.2
b) 4.9
c) 104
d) 24

D = 24

Step-by-step explanation:

The given quadratic equation is .

It is required to find the value of the discriminant. The value of discriminant  of any quadratic equation is given by :

Here, a = 1, b = -8 and c = 10

On plugging all the values, we get :

So, the value of discriminant for y is 24.
