Which expression represents adding four times a number (p) to its square?
Answer and explanation
Correct answer: \(p^2+4p\)
The square of the number \(p\) is \(p^2\), and four times the number is \(4p\). Since the question asks to add four times the number to its square, the expression is \(p^2+4p\). Option B uses subtraction, while option D multiplies the entire sum by 4. Exam tip: For phrases such as “add to,” use \(+\) and write the square and the multiple separately first.
