Comparing and Ordering Numbers
the set of all rational and irrational numbers
Real Numbers
This is what PEMDAS stands for (the math terms)
Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
The greatest factor that evenly divides into a set of numbers or monomials
Greatest Common Factor
How many terms are in this polynomial?
2x^2+345x-17
3
Any number that can be expressed as a fraction
Rational Numbers
Simplify
3^2(4-sqrt(4))
18
The smallest number or expression that is a common multiple of two or more numbers or algebraic terms
Least Common Multiple
What is the degree of this polynomial?
3x^4+5x^3+2x
4
Numbers that cannot be expressed as a ratio of two integers. Their decimal expansions do not terminate or repeat.
Irrational Numbers
Evaluate the following expression for x=2. Simplify completely.
2/(3*x^2)
1/6
Find the LCM of 4 and 8
8
What is the first thing you should always try when factoring?
Taking out a GCF
Put these numbers in order from smallest to largest:
pi
sqrt4
6/5
sqrt3
6/5
sqrt3
sqrt4
pi
This word means "plug in" and starts with an S
substitute
Find the GCF of
6x and 3x^2
3x
Why can you not use Difference of Squares here?
x^2+16
Because it is addition instead of subtraction
Which of these numbers is irrational?
3.14
71/28
sqrt2
273.413413413...
sqrt2
Evaluate the following expression for x=-1. Simplify completely.
3 abs(x^3+2)
3
Factor out the GCF. Don't forget the part in parentheses after the GCF.
12x^3+8x
4x(3x^2+2)
Factor. Write your answer in parentheses: (__)(__)
x^2-7x+10
(x-5)(x-2)
