Lesson 's Glossary: Binomial: Expression that has two (bi)
terms.
Depressed polynomial: The resulting
numbers of the synthetic division that correspond to the quotient of
the division; these are the coefficients for the Depressed polynomial that is one degree less than the divisor polynomial.
Completing the Square: Method that finds
the constant term in an incomplete perfect square trinomial of a
second degree equation to solve it.
Complex Conjugate Theorem: It states
that if we have an imaginary root in a one variable polynomial with
real coefficients, then we have another root at the complex
conjugate of this root. So if we have a + bi, the other root
is at a - bi.
Constant: It is a number or value that
remains always the same. Never changes.
Difference of two square: a2
- b2 = (a +b)(a - b)
Exponent: It is a raised number
representing the repeated multiplication of a given factor. Perfect
square trinomial: A trinomial generated by the product of two equal
binomials.
Expression: Any combination of numbers
and operations without the = sign.
Factoring: The process to brake a
polynomial down into the product of several factors.
Factors: All whole numbers that are
multiplied together to yield another number.
Factored Form: Any polynomial that is written as the product of polynomials of lower degree that may be obtained from the original polynomial.
Function: A relation of the type that
has exactly one value in the domain (independent variable) matching
a value in the range (dependent variable).
Function notation: A function written
with the symbol f(x) instead of y. It is read as f of x.
Like terms: Terms that have the same
combination of variables to the same power as factors.
Polynomial: A algebraic statement with
one or more terms. Word comes from “poly” which means many.
Polynomial (third degree): Geometric
representation. A third degree polynomial may be represented as the
volume of a rectangular prism for which length, width and depth are
the linear factors of the polynomial.
Power: Exponent of a number or variable.
Quadratic equation: An equation of the
form
ax2 + bx + c = 0 where a, b,
and c are real numbers and a is different from zero.
Quadratic formula: If ax2 +
bx + c = and a is different from zero then the quadratic formula is
given in terms of a, b, and c.
Quadratic function: Any function in the
form of
f(x) = ax2 + bx + c where a is different from zero. The
graph is a parabola and the largest exponent is 2.
Square Root: If x2 = y, then
x is the square root of y. Square root is the opposite of square.
Solution or root: The value that makes
an equation a true statement, a root refers particularly to the
value of x for which y = 0, this value is also the x-intercept of
the graph.
Term: A form of grouping one or more
numerical and/or variable factors by means of multiplication and
division. Addition and subtraction symbols separate terms.
Variable: A letter used to represent a
number. When the variable is part of an equation, it is possible to
find the value for which it stands for by solving the equation. This
is the solution (s) of the equation.
Variable expression: Mathematical phrase
with at least one variable in it.
Zeros of a function: The solutions for
the equation of the function when this equal to 0. The roots, also
known as the x-intercepts.
Zero Product Property: For the product
of any two real numbers; it means that at least one of them is zero,
so the product be equal to zero. This property allow us to solve
equations that are equal to zero; to be solved by factoring (linear
factors)
