Multiply аnd cоmpletely simplify the expressiоn. Enter yоur аnswer in stаndard form in the box below. 2x21+x2{"version":"1.1","math":"2x21+x2"} Some items, like this one, require a longer written response. There are two options for you to enter your answer. You can choose either method. The key is to clearly communicate your response. If I can understand it, I will grade it. The built-in Equation tool allows you to enter "nice" looking mathematical expressions. Click the + dropdown, then Equation, then Graphical Equation. This opens a set of templates. The first tab contains templates for exponents, fractions, radicals, and grouping symbols. When satisfied with your response, click Insert. You may edit your response any time prior to submitting your test by selecting it and re-opening the Equation tool. Take time on this practice test to explore using this tool, since the actual test is timed. You may also use keyboard symbols or type an accurate description of your answer. For example, to enter the expression x3xy {"version":"1.1","math":"x3xy "}, you can type "the absolute value of x cubed times the square root of xy," or something like that. It would also be fine to type |x^3|*sqrt(xy), using the ^ symbol for exponentiation and * for multiplication. Finally, I strongly advise sending me your scratch work after the test. I can't allow you to use your phone to take pictures or videos during the test, but you may scan and send your work to me by e-mail after submitting the test. When I have your written work (not just an answer, but how you got it), I'm able to assess partial credit for an incorrect result. If you only submit an incorrect answer, I have nothing else to assess. It is to your great advantage to SHOW WORK, even though this is an online exam. Now, answer the question...
