Please help me quick, im timed!

the 3rd option is the correct answer . u need to make the coefficient of x² the smallest before factorizing the equation.

C.

Step-by-step explanation:

After these two steps, we divide the whole expression by coefficient of (which is a) to both sides so that we get the isolated for further solving.

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 : )
