Week 11_Thu Quick Start

Simplify the exponential expression.

• 2x⁶y¹²
• 2x⁵y⁷
• 8x⁶y¹²
• 8x⁵y⁷

Simplify:
(3x - 5) ( 4x² - 2x - 3)

• 12x³ - 26x² - 25x + 15
• 12x³ - 20x² - 5x + 15
• 12x³ - 20x² - 6x + 15
• 12x³ - 26x² + x + 15

2x + 5(y - 1) when x=8 and y=5

• 20
• 31
• 36
• -4

3x² + 23x – 8

• (3x + 1)(x – 8)

• (3x – 8)(x + 1)

• (3x – 1)(x + 8)

• (3x – 1)(x – 8)

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)
