Adding and Subtracting and Multiplying Polynomials

Find the product:

(x - 1)(x - 8)

• x² + 9x + 8

• x² + 9x - 8

• x² - 9x - 8

• x² - 9x + 8

Simplify the expression.

-3x²(7x² - x + 4)

• -21x⁴ + 3x³ -12x²

• 7x² - x + 4 (-3x²)

• 21x⁴ + 3x³ + 12x²

• -12x² + 3x³ -21x⁴

Multiply

(x + 5)²

• x² + 25

• x² - 25

• x² + 10x + 25

• x² - 10x + 25

Find the product:

• 5x³ - 17x² + 24x +12

• 5x³ + 17x² - 24x +12

• 5x³ - 13x² + 24x +12

• 5x³ +13x² - 24x - 12

• 4x² + 2x

• 3x² + 3x

• 3x² + 2x

Add the following polynomials:

(x³ + 6x - 5) + (-6x² + 4x + 3)

• x³ - 6x² +10x - 8

• x³ - 6x² +10x + 2

• x³ - 6x² +10x - 2

• x³ + 4x - 2

What is the the standard form for the following expression?
-6x + 4x² - 13

• -13 - 6x + 4x²

• 4x²-6x - 13

• -13 + 4x² - 6x

• 4x² - 13 - 6x
