Vihaan finds that the roots of a quadratic equation that contains a difference of squares pattern is x = +-16. What is true about the graph of the parabola described by the quadratic equation? The graph contains two parabolas: one that touches the x-axis at x = 16 and one that touches the x-axis at x = -16.
The parabola crosses the x-axis at x = +-16.
The graph contains a parabola that does not have a vertex.
The parabola does not touch or cross the axis.

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.
