Ax² + x − 2 Bx² − x − 2 Cx² − x + 2 Next problem Made for Exam Preparation So a remainder of 0 means x + 3 divides it evenly? Milo Exactly — a remainder of 0 means x + 3 is a factor. Now look at your quotient: which two numbers multiply to −2 and add to −1?

But nobody else offers you the ability to just write without needing to constantly remind the chatbot about what you’re working on. Lessons tailored to your understanding ▾ Milo writes personalized lessons from your own practice — explanation, worked examples, and exercises pitched at your level. Lesson · Nonlinear functions Factoring quadratics You slipped on the sign of c in last week’s drills — remember: x² + bx + c factors into two numbers that multiply to c and add to b. Worked example x² − x − 2 → multiply to −2, add to −1 → (x − 2)(x + 1) ✓ Exercise · Nonlinear functions Now you — factor: x² + 3x − 10 A.(x + 5)(x − 2) B.(x − 5)(x + 2) Detailed progress tracking ▾ Study habits, competence by topic, and every problem practiced — shareable with a parent or teacher.
