Answer: 
is needed for 5 servings.
Step-by-step explanation:
Since we have given that
Hemal wanted to make desert for her family for which they made the recipe,
For 8 servings , the number of cups of flour is needed = 2
We will use "Unitary Method" ,
For 1 serving, the number of cups of flour is needed is given by
For 5 servings, the number of cups of flour is needed is given by
Hence, is needed for 5 servings.
The answer is down the page under ANSWER. here is a quick explanation first.
okay, i assume your equation is actually like this:
minus x squared plus 4 x minus
note: the proper way to type this electronically is: -x^2 + 4x - 2.
The equation you gave is known as a quadratic equation.
if you think about it, the generic (general) way of writing this quadratic equation is:
ax^2 + bx + c
a, b and c are just numbers
eg.
2x^2 + 7x + 4
looking at the general equation above
a is 2
b is 7
c is 4
you can put negatives in as well, to find out a, b and c
eg
-2x^2 - 6x - 12
so, what is a b and c?
a is -2 (must say its negative)
b is - 6 (must say negative)
c is - 12 ( again, remember its a negative number)
ANSWER
IF YOU JUST WANT THE ANSWER.
THE DISCRIMINANT IS:
4 squared minus (4 times -1 times -2)
this is 16 - 8
solution of discriminant is 8
explanation:
so, now we cleared that up.
in any quadratic equation ( like the equation you gave), the discriminant is (in general)
b2 - 4ac
use this to solve it for any quadratic equation for the discriminant
