Factoring Trinomials
The factoring trinomial form
The Factoring trinomial form is x2 + bx + c
In finding system of equations what are you solving for
Solving for x & y
What is this
2m4 - 7m2 - 5m + 1
Quadratic, Polynomial
If the x-values repeat, then is it a function?
NO
What is scientific notation?
A compact way of writing very large numbers or very small numbers; frequently used by scientist and mathematicians.
How do you solve the diamond method
The two sides should multiply to the top and add to the bottom
Solve
x + y = 3 3x + 2y = 14
y= -x + 3
3x + 2y = 14
-3x -3x
2y/2 =-3x/2 + 14/2
y = -3/2x + 7
Using addition solve
(11x - x2 + 13) + (2x2 - 23 - 5x)
x2 + 6x - 10
What is a Function
A special relationship between values: each input (x) has exactly an output (y)
Write 284,000 in Scientific notation
2.84 x 105
Solve using the diamond method
n2 + 9n + 20
20 on top 9 on bottom
(x+5) (x+4)
Using substitution solve for x and y
x - y = -10 x - 6y = -25
y = 3 x = -7
using subtraction solve
(4x2 + 5x) - (7x + 3x2 + 1)
x2 - 2x + 1
Is this a Function
(5,-2), (3,-5), (2,-5), (0,-2), (-1,-3)
Yes
Write 0.00000268 in scientific notation
2.68 x 10-6
Solve using diamond method
g2 + g - 6
-6 on the top 1 on the bottom
(x - 2) (x + 3)
Solve for x and y
x - 7y = -21 2x - 14y =-42
x = -28 y = -1
Solve
(4c - 11) - (4c + 11)
-22
Is this a function? why or why not?
(-2,3), (0,1), (2,-4), (3,-1), (2,4)
NO. This is not a function because the 2 value in the (x) place is repeated
Write 1.14 x 103 in standard form
1,140
Solve using diamond method
x2 - 14x - 51
-51 on top -14 on the bottom
(x - 17) (x + 3)
Using elimination solve for x and y
4x + 5y = 22 7x - 3y =-32
x = -2 y = 6
Solve
(3m2 + 7m -1) - (m2 + 2m - 5)
2m2 + 5m + 4
What is the vertical line test?
If a vertical line intersects a graph more than once, then it is NOT a function.
Use LARS
(9.5 x 107) + (1.1 x 106)
9.61 x 107
