Let's try to find at least one solution to .
Create a table of values. In column 1, enter the whole numbers between 0 and 10 to represent values of x. In column 2, evaluate the expression using the values for .
Compare your answer:
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | |
–35 | –36 | –35 | –32 | –27 | –20 | –11 | 0 | 13 | 28 | 45 |
We can see from the table that a solution to the equation is since at that value.
There is another number outside of 0 to 10 that would make the expression equal 0. Can you find it?
Enter the number outside of 0 to 10 that would make the expression equal 0.
Compare your answer:
The other zero for the equation is located at , but it is possible that you did not consider negative numbers.
