Algebra 3/4 delves into advanced algebraic concepts, including polynomial functions, rational expressions, and complex numbers.
After solving any algebra problem, plug your answer back into the original equation to see if it works. This simple habit can catch errors and boost your grade.
Compare your answer's form (like factored vs. expanded) to make sure it matches what's asked. If time allows, try another method to see if you get the same result.
After finding the roots of a polynomial, substitute them back into the equation to verify they make it zero.
If you simplify a complex fraction, multiply your answer by the denominator to check if you get the original numerator.
