• polynomial

Classify the polynomial and give the degree:

 $5x^2+10x$  

• Binomial, 3

• Trinomial, 3

• Trinomial, 3

• Binomial, 2

Find the sum. 

 $\left(2x^2-2x+3\right)+\left(3x^2+4x-5\right)$  

• 7x - 7x + 5x²

• 5x² + 2x - 2

• 5x²

• 5x² + 6x + 8

Find the difference. 

 $\left(2x^2-2x+3\right)-\left(3x^2+4x-5\right)$  

• x² + 6x + 8

• 2x² + 5x - 7

• -x2 - 6x + 8

• -2x² + 11x - 4

Find the product.

(x +2)(x + 3)

• x² + 5x + 6

• x² + x + 6

• x² + 5x + 5

• x² + 6x + 6

Factor: k² -2k - 24

• (k+4)(k-6)

• (k+4)(k+6)

• (k+6)(k-1)

• (k-4)(k+6)

Solve: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Factor: 3x² + 5x - 12

• (3x + 4)(x-3)

• (3x - 4)(x + 3)

• (3x + 3)(x -4)

• (3x - 3)(x + 4)

Solve: 3x² - 5x + 2 = 0

• x = ²/₃ and x = 1

• x = -³/₂ and x = -1

• x = ²/₃ and x = -1

• x = -²/₃ and x = -1
