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).

Step-by-step explanation:
If d=1,

If d=2,

If d=4,

Therefore,

When we say a rational number, this is a number that can be <span>written as a ratio. That means it can be written as a fraction, both the numerator and denominator whole numbers. Based on the given value above, I believe that the answer is considered as a rational number because it can be written as a fraction: 3 and 29/100. Hope this answer helps.</span>
