F.O.I.L.
This method uses a 2 x 2 grid to multiply 2 binomials.
What is the "BOX Method"?
This is the shape made by a quadratic equation.
What is a parabola?
These are the 2 numbers needed to factor
X2 + 5x + 4.
What is +4 and + 1 ?
It is the name of the highest or lowest point of a quadratic when graphed.
What is a VERTEX?
This is the letter in FOIL, when you multiply you will get the y axis intercept.
What is the letter "L" ?
This is the imaginary line that cuts a parabola in half when graphed.
What is the AXIS or LINE of SYMMETRY?
These are the 2 numbers needed to factor
X2 - 81.
What is +9 and - 9?
This is the axis of symmetry between the roots -2 and 10.
What is 4?
Multiply (x - 6)(x + 6) and you get this answer.
What is x2 - 36 ?
Surprise TRIVIA!!!! This is 212 degrees Fahrenheit.
What is the temperature F. that water boils?
When you factor the trinomial x2 - x - 42, this is the answer.
What is (x-7)(x+6) ?
These are the roots for the graph y = x2 +3x - 10.
What are - 5 and + 2 ?
This is the answer to (2x3 - .5)(2x3 + .5).
What is 4x6 - .25 ?
This is the word given to what the equation y = (x+8)2
will do on the x axis.
What is "BOUNCE"?
These are the 2 numbers used to factor
X2 - 47x - 150.
What are - 50 and + 3 ?
This is the axis of symmetry for the equation
y = (x-4)(x-20).
What is + 12 ?
When the degree = 1, it's called "linear".
When the degree = 2, it's called a "quadratic".
When the degree = 3, it is called this.
What is a "cubic"?
This is the axis of symmetry for y = x2 +5x - 14.
What is - 2.5 ?
