II.
Find the Greatest Common Factor:
1. 12 and 20
|
2. 25 and 75 | 3. 42 and 48 | 4. 400 and 600 | 5. 39 and 52 | 6. 90 and 135 |
III.
Reduce:
1. 12 / 20
|
2. 25 / 75 | 3. 42 / 48 | 4. 400 / 600 | 5. 39 / 52 | 6. 90 / 135 |
IV.
Factor, using the Distributive Property:
1. 12x2 – 30 x
|
2. 40x3 – 4x2 | 3. 6xy + 12x2 y2 |
V.
Factor these trinomials: (Problems 1-5)
1. x2 + 7 x + 12
|
2. 12x2 – 7 x -12 | 3. Common Factor
6x2 – 46 x + 28 |
4. Perfect Square
16x2 – 40 x + 25
|
5. variable is a binomial
3(x-8)2 - (x-8 ) - 14 |
6. factor by Grouping
ax + 2a + bx + 2b |
VI.
Use factoring to Reduce:
1. 4 x2
/ (6 x2 - 8x)
|
2. (2x2 – 18) / (2x2 + 2 x -24) | 3. (4x2 – 12x +9) / (2x2 + 11 x -21) |
VII. Use factoring to Solve Equations: Remember:
Simplify, arranging all terms on one side, in descending order.
Factor out common factors.
Set one side equal to zero
Factor
Set each factor equal to zero, making small equations.
Solve the small equations, to find the possible values of the variable.
Check.
1. 2x2 – 16 x = 0
|
2. x2 + 7x = 60 | 3. 3x2 + 14 = 23 x |
4. Common Factor.
10x2 - 5 x - 225 = 0
|
5. Difference of Squares.
4x2 - 81 = 0 |
6. Double Root.
x2 - 20 x + 100 = 0 |
