Axis of Symmetry - 🧠 ANSWER ✔✔For a quadratic function the axis of
symmetry is a vertical line that passes through the vertex of a parabola.
From standard form the axis of symmetry can be found using the formula
x= -b/2a
From vertex form - the axis of symmetry is
x=h
From intercept form, the axis of symmetry is half-way between the x-
intercepts at
,x= (p+q)/2
Binomial - 🧠 ANSWER ✔✔A polynomial with two terms.
Example: 12x + 9
Coefficient - 🧠 ANSWER ✔✔a constant quantity placed before and
multiplying the variable in an algebraic expression
example: 5x+7
Completing the Square - 🧠 ANSWER ✔✔A quadratic function
Equation should be in this form
Ax2 +bx = c
And "a"=1
, Take 1/2 of b, square it, add it to both sides
Factor the left side, simplify the right
Take the square root of each side and find the solutions
Complex Number
any number that can be written as a + bi, where a and b are real numbers
and i = √-1
Constant Term - 🧠 ANSWER ✔✔A term that has a number part but no
variable part.
The ___ of the algebraic expression 3x²+ 5x + (-7) is (-7).
Cube Root - 🧠 ANSWER ✔✔A number written as whose cube is x
Degree - 🧠 ANSWER ✔✔Number of times a variable is used to multiply
(exponents).
Difference of Two Cubes - 🧠 ANSWER ✔✔A method of factoring a binomial
(that's using subtraction) when both terms are cubes.
