This math topic focuses on practicing the multiplication of algebraic expressions with bracketed terms that involve different variables. It targets skills in expanding expressions such as \((y - 3)(c + 5)\) or \((b + 4)(x - 6)\), and identifying equivalent forms of these products. Each problem presents an expression in a format such as \((variable1 ± constant) (variable2 ± constant)\) and asks to select the correct expanded form from provided options. By tackling these exercises, students enhance their understanding of distributing across terms and handling algebra with different variables.
