If (p(x)=4x-9) and (q(x)=3x+2), what is (p(x)+q(x))?

Answer and explanation

Correct answer: \(7x-7\)

While adding polynomials, add like terms. Here, \(4x+3x=7x\) and \(-9+2=-7\), so \(p(x)+q(x)=7x-7\). Option \(7x+11\) results from incorrectly adding the constant terms. Exam tip: add the \(x\)-terms and constant terms separately.
