Question

Use the table method to multiply a binomial with a trinomial.
(2𝑥 − 5) (−3𝑥2 + 4𝑥 − 7)

The correct answer is: -6x3 + 23x2 - 34x + 35.


    Answer:

      • Given:

     (2x - 5) (-3x2 + 4x - 7)

    • Step 1:


    • Step 2:
    Add all terms:

    (-6x3 + 8x2 - 14x + 15x2 - 20x + 35)

    = -6x3 + 23x2 - 34x+ 35
    Hence,

    (2x - 5) (-3x2 + 4x - 7) = -6x3 + 23x2 - 34x+ 35

    • Final Answer: 

               -6x3 + 23x2 - 34x+ 35.
