Question
Use the table method to multiply a binomial with a trinomial.
(−3𝑥2 + 1) (2𝑥2 + 3𝑥 − 4)
The correct answer is: -6x4 – 9x3 + 14x2 +3x-4
Answer:
- Given:
(-3x2 + 1) (2x2 + 3x - 4)
- Step 1:
- Step 2:
Add all terms:
(-6x4 – 9x3 + 12x2 + 2x2 + 3x – 4)
= -6x4 – 9x3 + 14x2 +3x-4
Hence,
(-3x2 + 1) (2x2 + 3x – 4) = -6x4 – 9x3 + 14x2 +3x-4
- Final Answer:
-6x4 – 9x3 + 14x2 +3x-4
- Given:
Hence,
