The resulting expression on factorization by grouping method is (3-7x²)(x-3).
<h3>What is Factorization?</h3>
Factorization is a method in which an Integer or an expression is written in terms of product of its fractions.
The expression given in the question is
–7x³ + 21x² + 3x – 9
This equation has to be factorized using grouping method.
group of two or more is formed and common term is taken out.
-7x² (x -3) +3(x-3)
( -7x²+3) (x-3)
(3-7x²)(x-3)
The resulting expression on factorization by grouping method is
(3-7x²)(x-3).

For question between 13 -> 17 replace n with the number.
Example:
13.) n = 2; 2+(-1) = 1
Answer:
-3
Step-by-step explanation:
1. rearrange so it's in the formula y=mx+C
2. y=-3x+5
y=mx+C
M=gradient
-3=m
gradient= -3
