Mathematics>Standard Multiple Choice
Read the following question and then select the best answer.
Which of the following is equivalent to the above expression?
Choice C is correct. First, notice that some of the answer choices given are polynomials in standard form and some are in factored form. Start by combining like terms and then determine if the resulting polynomial can be factored.
Like terms in a polynomial are terms that have the same variable part raised to the same power. Combine the like terms in the above expression to obtain the following polynomial.
Since this is not an answer choice, determine if the polynomial can be factored.
The equivalent expression is
