Can sum one me this is my last question

Option B is correct.

the value of discriminant is, -7

Step-by-step explanation:

Given the equation:

To find the value of discriminant

A quadratic equation is of the form where a, b and c are coefficient of the equation.

On comparing with given equation we have;

a  = 1 , b = 1 and c = 2

then;

Discriminant =

Therefore, the value of discriminant is, -7

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

i don't even know man. edge inuity be messing with us. i had to ask a question too.
