Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc
Answer:
Step-by-step explanation:
(2n -3)(2n+1) = 4n^2 + 2n - 6n - 3 = 4n^2 - 4n -3
Answer:
-5/2 x -33/4
Step-by-step explanation:
(-11/2 x + 3) -2 (-11/4 x -5/2)
(-11/2 x + 3/1) -2 (-11/4 x -5/2)
The LCM of 2 and 1 is 2, and the LCM of 4 and 2 is 4.
(-11/2 x + 6/2) -2 (-11/4 x -20/4)
( -5/2x) -2 (-31/4)
-5/2x -2 -31/4
-5/2x -2/1 -31/4
LCM of -2 -31/4 is 4
-2/4 -31/4
-33/4
-5/2x -33/4 in simplest form.
Addition is the correct answer.
x^2 is the part where you get the second degree term. If you add x^2+x^2 you get 2x^2. If you subtract x^2-x^2 you get 0. If you multiply x^2*x^2 you get x^4, which is a fourth degree term
