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.
\(3(x – 1) + 5(x + 4)\)
\(= 3x – 1 + 5x + 4\)
\(= 8x + 3\)
Answer:
(i) The simplification is .
(ii) The reason is .
(iii) \(3(x – 1) + 5(x + 4)\) \(=\) .
