Polynomials

100

Add the two polynomials.

3x³ + 2x² - x - 7  and  x³ - 10x² + 8

4x³ - 8x² - x + 1

200

Subtract the two polynomials:

(8x³ - 3x² - 2x + 9) - (2x³ + 6x² - x + 1)

6x³ - 9x² - x + 8

300

Multiply the two binomials:

(2x + 3)(x - 4)

2x² - 5x - 12

400

Multiply the polynomials:

(x + 2)(x² - 2x + 3)

x³ - x + 6

500

Multiply the polynomials:

(x - 1)(x + 4)(x + 5)

x³ + 8x² + 11x - 20

Factoring

100

x² + 3x + 2

(x+1)(x+2)

200

x² - x - 12

(x - 4) (x + 3)

300

 6x² + 11x + 4

(2x + 1) (3x + 4)

400

8x² + 6x - 9

8x² + 6x - 9 = (4x - 3) (2x + 3)

500

9x² - 27x + 20

9x2 - 27x + 20 = (3x - 5) (3x - 4)

Solve for X

100

Solve for x: 

x² + 2 = 18

x = 4 or x = -4

200

Solve for x: 

x³ - 4x² + 4x = 0

x = 0 or x = 2

300

Solve for x: 

2x³ = 50x

x = 0, x = 5, or x = -5

400

Solve for x: 

x⁴ + 36 = 13x² 

x = 2, x = -2, x = 3, or x = -3

500

Solve for x: Find all Complex solutions.

x⁵ + x³ - 2x² - 12x - 8 = 0

x = -1, x = -1, x = 2, x = 2i, and x = -2i
