Answer:
(2x^2-7)(x+3)
Explanation:
Now, when we write a polynomial, we write it from high order to low order, which the polynomial is already in that form. Then, we factor the first and last two terms.
To factor 2x^3 and 6x^2, 2x^2 is the common factor
2x^2(x+3)-7x-21
in -7x-21, -7 is the common factor, so our end result is
2x^2(x+3)-7(x+3), and this can be rewritten as:
(2x^2-7)(x+3)
