(X-2)(X-1)
To do this, first you want to notice that there is no number in front of the x^2.
This will not work on its own if there is
Find 2 numbers that multiply to 2 and add to -3
-3 is in front of the x and 2 is alone in the equation so those are the numbers you are using
-2 and -1 are the only whole numbers that do that
-2 + -1 = -3
-2 * -1 = 2
Answer:

Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that

Multiply both sides by 5


Multiply both sides by Area{circle}


Substitute the areas of sector and circle with their respective formulas;


So, we have

Divide both sides by 


Multiply both sides by 360


Divide both sides by 5




Hence, the central angle is 216 degrees
