We have expanded and simplified some algebraic expressions below to their simplest forms.
(i) Check each of the simplifications and see if there is a mistake.
(ii) If there is a mistake, try to explain what could have gone wrong.
(iii) Then write the correct expression.
\(-3p (–9p + 3q)\)
\(= 6p – 3q\)
\(= –3p + 9p – 3q\)
\(= 6p – 3q\)
Answer:
(i) The simplification is .
(ii) The reason is .
(iii) \(-3p (–9p + 3q)\) \(=\) .
