Terms/Methods/Formulas

Question 1

Lesson 8.8- Factor difference of squares

Answer 1

a^2- b^2= (a+b)(a-b)
Or
(a-b)(a+b)

Ex. Factor 2x^4-32

Question 2

Binomial

Answer 2

Two terms in an expression

Question 3

Trinomial

Answer 3

Three terms in an expression

Question 4

Monomial

Answer 4

One term in an expression

Question 5

Quadratic equation

Answer 5

Find the solutions to a problem:

X^2-36x+26=0

Formula:
-B+or- the square root of {b^2-4(a)(c)}
Over 2(a)

Question 6

Scientific formula

Answer 6

42,000,000=

42x10^6

Question 7

Absolute value

Answer 7

Distance a number is from zero on a number line

Question 8

Additive identity

Answer 8

For any number a, a + 0 =0 + a= a

Question 9

Algebraic expression

Answer 9

An expression consisting of one or more numbers and variables along with one or more operations

Question 10

Power property of equality

Answer 10

If you square both sides of a true equation, the resulting equation is true

If a=b, then a^2=b^2

If (square root of X)= 4, then (square root of X)^2=4^2
Thus, X=16
