Determine the discriminant for the quadratic equation 0=-2x^2+3. Based on the discriminant, how many real number solutions does the equation have? Discriminant = b^2-4ac

2 solutions

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Standard Form: ax² + bx + c = 0

Discriminant: b² - 4ac

Step-by-step explanation:

Step 1: Define

-2x² + 3 = 0

Step 2: Identify

a = -2

b = 0

c = 3

Step 3: Find

NO REAL SOLUTIONS

Step-by-step explanation:

a=2 b=0 c=3

0-4(2)(3)=0-24=-24. Since the discriminant is negative, there are NO REAL SOLUTIONS.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
