Step-by-step explanation:
Before we begin answering, we need to go over the rules of multiplying polynomials.
Unlike in regular multiplication, we have to combine the like terms in the subtracting portion of the multiplication process.
Another rule is that when there are more than 1 variable in a term, we need to take the variables as two separate variables and then proceed to multiply them.
Answer:
Ration is an ordered pair of numbers that show a comparison between two things.
You must have 4 terms for factoring by grouping to be easier to use.
For example...
x^2 + 10x + 2x + 20
(x^2 + 10x) + (2x + 20)
x(x+10) + 2(x+10)
(x+2)(x+10)
The first line, the expression x^2+10x+2x+20, has four terms.
Note: Just because you have four terms doesn't automatically guarantee you can factor
The little square means a right angle which is equal to 90 degrees.
X + 30 = 90
X = 60 degrees
