Multiplying Polynomials (part 1)

Simplify:
2x ( -2x -3)

• -4x - 3
• x² - 3
• -4x² - 6x
• -4x - 6

Multiply  7x²y³ (2x⁴y⁵+6xy³)

• 14x⁸y¹⁵+42x²y⁹
• 9x⁶y⁸+13x³y⁶
• 14x⁶y⁸+42x³y⁶
• 14x⁶y⁸+42x²y⁶

(x + 5)(x + 4)

• x² + x + 20
• x² + 20x + 9
• x² + 9x + 20
• x² - 9x + 54

(2x - 1)(x + 2)

• 2x² + 3x - 2
• 2x² - 5x - 2
• 2x² + 3x + 2
• 2x² - 5x + 2

(x - 7)(x + 7)

• x² + 7x - 49
• x² - 7x + 49
• x² - 49
• x² + 49

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

• -21x⁴ + 3x³ -12x²
• 7x² - x + 4 (-3x²)
• 21x⁴ + 3x³ + 12x²
• -12x² + 3x³ -21x⁴
