Multiplying Polynomials

Multiply.

(x + 5)(x + 4)

• x² + x + 20

• x² + 20x + 9

• x² + 9x + 20

• x² - 9x + 54

Simplify the expression.
-3x²( 7x² - x + 4)

• -21x⁴ + 3x³ -12x²

• 7x² - x + 4 (-3x²)

• 21x⁴ + 3x³ + 12x²

• -12x² + 3x³ -21x⁴

(x - 5)(x + 1)

• x² - 4x - 5

• x² + 6x - 5

• x² - 5x - 4

• x² - 4x - 4

Write the expanded (general) form of the product (x+3)(x+6).
