Factoring and Solving
Factor:
16x + 24x^2y
8x(1 + 3xy)
Simplify:
(n + 4)(n - 4)
n^2 - 16
3x + 4(7x - 4) = 139
x = 15
Add:
3/5 + 1/3
14/15
Factor:
4x^2y + 14xy - 18y
2y(2x + 9)(x - 1)
Solve:
2m^2 - 50 = 0
m = 5, m = -5
Multiply:
4x(3x^2 - 12xy)
12x^3 - 48x^2y
Solve:
3x + 6(x - 8) = -129
x = -9
Subtract
9/10 - 3/4
3/20
Factor:
12x^2 - 43x +10
(4x - 1)(3x - 10)
Solve:
2n^2 - 4n - 70
n = -5, n = 7
Multiply:
(n + 2)^2
n^2 + 4n + 4
2x - 2(7x + 18) = -96
x = 5
Add, answer must be written as a mixed number
3 3/4 - 2 1/5
1 11/20
Factor:
x^3 - x^2y - xy^2 + y^3
(x + y)(x-y)^2
Factor:
3x^2 + 30xy + 27y^2
3(x + 9y)(x +y)
multiply:
- 1/2xy( 6x^3 - 12x^5y + 8)
-3x^4y + 6x^6y^2 - 4xy
Solve:
-6x - 4(-3x - 4) = -20
x = -6
Add, write your answer as a mixed number in simplest form.
4 3/4 + 5 2/3
10 5/12
Factor:
2x^5y - 14x^3y - 36xy
2xy(x^2+2)(x+3)(x−3)
Factor:
3x^2y + 2x^2 - 8 - 12y
(3y + 2)(x - 2)(x +2)
Multiply and Simplify
2(4x^2y - 8x) - 4x(3xy - 2)
-4x^2y - 8x
Solve:
1/2(4x + 2) - 2/3(6x + 9) = 13
x = -9
Subtract, write your answer as a mixed number in simplest form.
5 1/4 - 2 3/10
2 19/20
Factor:
4x^3 - 12x^2y - 9x + 27y
(x - 3y)(2x - 3)(2x+3)
