<u>1.Example, x²-25 can be factored as (x+5)(x-5).</u>
<u>
</u>
<u>2.This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).</u>
<u>
</u>
<u>3.When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5).</u>

140 / 100 * X = 56
X = 56 * 100 / 140 = 5600 / 140 = 40

Answer:
Step-by-step explanation:
The general equation of the circle is:
(x-h)²+(y-k)²=r²
(h, k)=(-3,-5) are the coordinates of the center of the circle.
r=6 is the radius
The equation of the circle is:
(x+3)²+(y+5)² = 36
You plug in the number for x and if it is equal to the solution then it is correct
