How many terms are in a trinomial?
DAILY DOUBLE
Three
(x + 5) + (3x + 9)
4x + 14
(7x + 4) - (5x + 8)
2x - 4
Solve the system of equations (use substitution or elimination):
y = 3x - 2
y = - x - 6
DAILY DOUBLE
(-1, -5)
(3x2 + 4x) + (2x2 - 3x)
5x2 + x
(6x2 + 4) - (3x2 + 5)
3x2 - 1
Simplify: √49u10
7u5
(-4x2 + 2x - 3) + (5x2 - 4x + 8)
x2 - 2x + 5
(2x - 4) - 2(4x - 2)
DAILY DOUBLE
- 6x
(2x - 4)(3x2 - 6x + 1)
6x3 - 24x2 + 26x - 4
Convert to slope-intercept form: 4y - 8x = 24
y=2x+6
Write an example of a polynomial with 4 terms and degree of 3.
Mr. Myhre will check!
(8x2 - 4x + 3) + (7x2 + 2x - 11)
15x2 - 2x - 8
(6x2 - 5x + 8) - (4x2 - 7x + 9)
2x2 + 2x - 1
(2x2 - 4x + 6)(x2 + 5x - 2)
DAILY DOUBLE
2x4 + 6x3 - 18x2 + 38x - 12
Y varies directly as x. When y = 12, x = - 2. What is y when x = 3? Formula: y = kx
y = - 18
Like terms need to have...(two things!!)
1. Same variables 2. Same exponents
(5x3 + 4x2 - 2x + 2) + 2(2x3 - 2x2 + x + 5)
9x3 + 12
(6x3 + 4x2 - 4x + 5) - 2(2x3 - 3x2 + 5x - 5)
2x3 + 10x2 - 14x + 15
Mr. Myhre wants to know how many desks can fit in his classroom next year. The length of his classroom is x + 5 ft and the width is x - 4 ft. What is the area of his classroom? Area = lw
*Answer MUST be labeled correctly!*
x2 + x - 20 square ft
Simplify : (54x - 3)(52x + 1)
56x - 2
