Example Question #241 : High School: Algebra
What are the -intercept(s) of the function?
To find the -intercept of a function, first recall that the -intercept represents the points where the graph of the function crosses the -axis. In other words where the function has a value equal to zero.
One technique that can be used is factorization. In general form,
where,
and are factors of and when added together results in .
For the given function,
the coefficients are,
therefore the factors of that have a sum of are,
Now find the -intercepts of the function by setting each binomial equal to zero and solving for .
To verify, graph the function.
The graph crosses the -axis at -5, thus verifying the result found by factorization.
Example Question #1 : Polynomial Identities And Numerical Relationships: Ccss.Math.Content.Hsa Apr.C.4
Use FOIL for the following expression.
The first step is to rewrite the problem as follows.
Now we multiply the first parts of the first and second expression together.
Now we multiply the first term of the first expression with the second term of the second expression.
Now we multiply the second term of the first expression with the first term of the second expression.
Now we multiply the last terms of each expression together.
Now we add all these results together, and we get.
