Q3. The standard form coefficients of 1x^2 + (-4)x + (3) = 0 are (a, b, c) =
- A.(3, -4, 1)
- B.(1, 3, -4)
- C.(-4, 1, 3)
- D.(1, -4, 3)
Answer: D. (1, -4, 3)
Spot-the-setup - a typical math numerical. The data on the table: 1, 2, -4, 3, 0. We are after the quantity the stem asks for. Tool of choice - compare with ax^2 + bx + c = 0 to read off a=1, b=-4, c=3. Rearrange it for the unknown before substituting. Numbers in: compare with ax^2 + bx + c = 0 to read off a=1, b=-4, c=3. Lock in option D) (1, -4, 3).
