Question 1
Expand 3(2x + 5).
- A) 6x + 5
- B) 6x + 15
- C) 2x + 15
- D) 5x + 15
Show answer
Answer: 6x + 15
Multiply the term outside the bracket by each term inside: 3 x 2x = 6x; 3 x 5 = 15. Result: 6x + 15.

Question 2
Expand (x + 3)(x + 2).
- A) x^2 + 5x + 6
- B) x^2 + 6x + 5
- C) x^2 + 5
- D) x^2 + 5x + 5
Show answer
Answer: x^2 + 5x + 6
FOIL: First (x x x = x^2), Outer (x x 2 = 2x), Inner (3 x x = 3x), Last (3 x 2 = 6). Sum: x^2 + 5x + 6.

Question 3
Expand (x - 4)(x + 1).
- A) x^2 - 3x - 4
- B) x^2 + 3x + 4
- C) x^2 - 5x - 4
- D) x^2 - 3x + 4
Show answer
Answer: x^2 - 3x - 4
FOIL: x x x = x^2; x x 1 = x; -4 x x = -4x; -4 x 1 = -4. Sum: x^2 + x - 4x - 4 = x^2 - 3x - 4.
