Question

Antonia is factoring the polynomial, which has four terms.

Answer 1

Answer:

3(x - 3)(7x^2 + 5).

Step-by-step explanation:

21x3 - 63x2 + 15x - 45

The greatest common factor of the constants is 3, so we have:

3(7x^3 - 21x^2 + 5x - 15)    

Now we factor this by grouping:

= 3 [7x^2 (x - 3) + 5(x - 3)

= 3(x - 3)(7x^2 + 5).

Answer 2

Answer:

Step-by-step explanation:

It looks like the terms are:

(7x2 + 5) and (x - 3)
