Answer:
(25a2c - 15a2d - 10cb + 6db)
Step-by-step explanation:
Equation at the end of step 1: (((75•(a2))•c)-((32•5a2)•d))-30cb)+18db
STEP 2:Equation at the end of step2: ((((3•52a2) • c) - (32•5a2d)) - 30cb) + 18db
STEP3:
STEP 4:Pulling out like terms
4.1 Pull out like factors :
75a2c - 45a2d - 30cb + 18db =
3 • (25a2c - 15a2d - 10cb + 6db)
To introduce to you, polynomials are algebraic equations containing more than two terms. The degree of a polynomial is determined by the term containing the highest exponent. When arranged from the highest to the lowest degree, the leading coefficient is the constant beside the term with the highest degree. An example would be: 2x² + 5x +6. The degree of this polynomial is 2 and the leading coefficient is also 2 from the term 2x².
For even-degree polynomials, the graphs starts from the left and ends to the right on the same direction. If the graph enters the graph from the up, the graph would also extend up to infinity. If the leading coefficient is positive, the graph starts and ends on the upward direction. When it's negative, it starts and ends below.
For odd-degree polynomials, the start and end of the graph are in opposite directions. If it starts from below, it will end extending upwards. When it comes to leading coefficients, a positive one would have a graph that starts downward and ending upwards. The opposite is true for the negative leading coefficients.

Probability sampling simply illustrates a scenario where the subjects of the population have an equal opportunity.
<h3>What is probability sampling?</h3>
Probability simply means the likelihood of the occurence of an event.
In this case, in probability sampling, the subjects of the population have an equal opportunity.
In non-sampling, an equal opportunity isn't given.
