If (p(x)=60+9x) and (q(x)=14x-10), when will (p(x)) and (q(x)) be equal?

Answer and explanation

Correct answer: \(x=14\)

For the two polynomials to be equal, \(60+9x=14x-10\). Rearranging gives \(70=5x\), so \(x=14\). Substituting \(x=14\) gives \(186\) for both polynomials. \(x=13\) is a close distractor, but the two values are not equal there. Exam tip: In equality questions, equate the expressions and collect the variable terms on one side.
