8.1-8.2 Distributing Monomials Simplifying and classifying.

Simplify:

2x(x - 5)

• 2x - 5

• 2x - 10

• 2x² - 10x

• None of these answers are correct.

Find the sum.
(2x² + 5x - 7) + ( 3 - 4x² + 6x)

• 2x² + 3x +1
• -2x² - 11x -4
• 2x² + 5x -7
• -2x² + 11x -4

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

rewrite the following in standard form:

2x² - 3x + 1

• 3x - 2x² + 1

• -3x + 2x² +1

• 1 + 2x² - 3x

• Its already in standard form
