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.
\(4(x – 1) + 6(x + 8)\)
\(= 4x – 1 + 6x + 8\)
\(= 10x + 7\)
Answer:
(i) The simplification is .
(ii) The reason is .
(iii) \(4(x – 1) + 6(x + 8)\) \(=\) .
