What is the formula for Factorizing Quadartics?
|
State the values of a , b and c.
Find the product (a*c) and the sum(b). Find 2 numbers that when multiplied give (p) and when added gives (s). Then Factorize. |
|
|
How do you complete the square?
|
The general form is : a(x+h)^2+k
where h= b/2a and k= 4ac-b^2/4a |
|
|
What is the Quadratic formula?
|
x=
-b+ - (the square root of) b^2 - 4ac (divided by) 2a |
|
|
How do you solve a quadratic graphically?
|
If a<0 (if a is negative) then it's a maximum curve. (n). If a>0 (if a is positive) then it is a minimum.(u)

|
A(x1, y1) and B(x2, y2).
AB(x1+x2/2 , y1+y2/2). |
|
|
Gradient of a line formula is?
|
= y2-y1/x2-x1
|
|
|
Finding th e equation of a straight line formula is?
