Solve the equation x² − 2x = 0.
- A. x = 0 or x = 2
- B. x = 2 only
- C. x = 0 or x = −2
- D. x = ±√2
Verified working — step 1
Factorise: x(x − 2) = 0. A product is zero when either factor is zero, so x = 0 or x = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
