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

Answer 1

Answer:

D = 24

Step-by-step explanation:

The given quadratic equation is $y=x^2-8x+10$.

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

$D=b^2-4ac$

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

On plugging all the values, we get :

$D=(-8)^2-4\times 1\times 10\\\\D=24$

So, the value of discriminant for y is 24.
