Question 11 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.When multiplying two binomials (two brackets), you must multiply every term in the first bracket by every term in the second bracket. Correct solution (๐+2)(๐+4) =๐(๐+๐)+๐(๐+๐) =๐๐+4๐+2๐+8
