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
