Question

3. Simplify the following:
→ (2x – 3y) (3x + y) + (x + 2y) (x - y)

→ (p + q) (p2 - 0) + (p - 9) (p + ?)

→ (x + 2y) (- 3x - y) - (x + y) (x - y) + (x – 2y) (- 2x + y)

→(a + b) (a + b) - (a - b)(a - b)​

Answer 1

$(2x - 3y) (3x + y) + (x + 2y)(x - y)$

$= 2x \times y( - 5y + 3x) + (x - y)2y$
