When asked to simplify the following expressions, a student came up with the following plans. Unfortunately, they are incorrect. Point out what is wrong and give correct answers. a) Simplify x/x+4 if possible. The student: Split the expression into two fractions and then simplify each: x/ x+4 = x/x + x/4 = 1 + x/4 b) Simplify t³-2t/ t Divide the common factor t into t³: t³-2t / t = t² - 2t
