Expand 8x(x − 5).
A 8x² − 5
B 8x² + 40x
C 8x − 40x
D 8x² − 40x
Correct answer: D — 8x² − 40x
- Multiply every term inside the bracket by the term outside.
- 8x(x − 5) = 8x² − 40x.
- Why the other options are wrong:
- A (8x² − 5): Did not multiply the second term by 8x.
- B (8x² + 40x): Used the wrong sign.
- C (8x − 40x): Multiplied x by x and got x, not x².
Skill: Expanding brackets
