Question 2
Complete the table:
$\begin{matrix} First expression & Second expression & Product (i) & a & b + c + d & - - (i i) & x + y - 5 & 5 x y & - - (i i i) & p & 6 p^{2} - 7 p + 5 & - - (i v) & 4 p^{2} q^{2} & p^{2} - q^{2} & - - (v) & a + b + c & a b c & - - \end{matrix}$

Solution

$\begin{matrix} First expression & Second expression & Product (i) & a & b + c + d & a (b + c + d) = a \times b + a \times c + a \times d = a b + a c + a d (i i) & x + y - 5 & 5 x y & 5 x y (x + y - 5) = 5 x y \times x + 5 x y \times y - 5 x y \times 5 = 5 x^{2} y + 5 x y^{2} - 25 x y (i i i) & p & 6 p^{2} - 7 p + 5 & p (6 p^{2} - 7 p + 5) = p \times 6 p^{2} - p \times 7 p + p \times 5 = 6 p^{3} - 7 p^{2} + 5 p (i v) & 4 p^{2} q^{2} & p^{2} - q^{2} & 4 p^{2} q^{2} (p^{2} - q^{2}) = 4 p^{4} q^{2} - 4 p^{2} q^{4} (v) & a + b + c & a b c & a b c (a + b + c) = a b c \times a + a b c \times b + a b c \times c = a^{2} b c + a b^{2} c + a b c^{2} \end{matrix}$
