What is the value of the discriminant for the quadratic equation –3 = –x2 2x? discriminant = b2 – 4ac –8 4 8 16

we know that

The formula to solve a quadratic equation of the form is equal to

the discriminant is equal to

in this problem we have

so

substitute the values

therefore

the answer is

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
