HKDSE Math · Paper 1 style
Solve 2x² − 5x − 3 = 0.
x = 3 or x = ½
x = 3
x = 3 or x = −½
x = −3 or x = ½
Your factorization was right, but the answer needs both roots. You dropped the negative root, x = −½. We've added two similar questions to your queue.

What Learners Say
“I drill DSE Math topic by topic after school. When an answer is wrong, the grading points to the step that lost the mark, so I know exactly what to fix before the next set.”

“I can't teach P5 Math myself, so my daughter practices on thinka and the explanations do the teaching. The dashboard shows me which topics keep coming back.”

Is thinka free?
Free accounts include daily practice with no credit card required. Upgrading removes limits and adds deeper analytics, and you can cancel whenever you like.
How accurate is AI grading for DSE long questions?
The grading follows marking-scheme structure step by step: where marks were gained, where they slipped and what a stronger answer would include. It responds to what you actually wrote rather than comparing you against a single model answer.
