Yes I’m dumb sorry but just help PLEASE

Case 1:    2 solutions

Case 2:    1 solution

Case 3:    none/imaginary solutions

Step-by-step explanation:

The discriminant comes from the square root section of the quadratic formula:

   (ignore the Â, it's a formatting error)

The quadratic formula is used to find the solutions for quadratic equations. Quadratic equations are in the format ax² + bx + c. To solve for "x", you would substitute "a", "b" and "c" into the formula.

Why the discriminant works:

When you have to square root a number, it has to be positive inside the root (or else you get imaginary numbers).

Example: (if the inside of the root is less than 0)

If b = 4, a = 5, c = 1 :

b² - 4ac

= 4² - 4(5)(1)

= 16 - 20

= -4

√-4 is imaginary. The quadratic equation has no solutions because you can't do the rest of the quadratic formula.

Example: (inside of the root is 0)

If b = 4, a = 4, c = 1 :

b² - 4ac

= 4² - 4(4)(1)

= 16 - 16

= 0

There will be one solution. In the quadratic formula, this affects where there is a ± sign. See the formula again.

   If the square root area equals 0:

             Adding and subtracting 0 give the same answer.

Therefore there is only one solution.

Example: (inside of the root is greater than 0)

If b = 4, a = 3, c = 1 :

b² - 4ac

= 4² - 4(3)(1)

= 16 - 12

= 4

There will be two solutions. Notice where the ± sign is again in the uadratic formula.

       Substitute the answer for b² - 4ac

          You can get two different answers between adding and subtracting 2.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
