<h3>
Geometric sequence.</h3>
A geometric sequence goes from one term to the next by always multiplying or dividing by the constant value except 0. The constant number multiplied (or divided) at each stage of a geometric sequence is called the common ratio (r).
We have:

Find the common ratio:

<h3>The formula of the n-th term of a geometric sequence:</h3>

Answer:
Step-by-step explanation:
The first thing you want to do is to factor in any quadratic equation.
So, -10(x^2-25)
Now, we see this is a special case, whenever we see a equation in this case, x^2 - b^2, we factor it to this (x+b)(x-b)
So, -10(x+5)(x-5)
x = -5 and x = 5
The slope of the line defined by the equation 3x-y=0 solution is 3 .
Answer:
5(x - 5y)(x + 5y)
Step-by-step explanation:
Note that 5 is common to both terms. Thus,
5x² - 125y² = 5(x² - 25y²).
Also note that x² - 25y² is the difference of two squares and has factors (x - 5y) and (x + 5y).
In fully factored form, 5(x² - 25y²) is:
5(x - 5y)(x + 5y)
36 is probably the answer sorry if I’m wrong :)
