• -3
• 5
• 6

Add the following polynomials:
(x³-2x²+3)+(2x³+3x²-1)

• 3x³-2x²+3x+2
• 3x³+x²+2
• 3x³-5x²-2
• 3x³-x²+1

Subtract the following polynomials:
(3x²-3x+2)-(x²-2x+1)

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

Factor completely: 3x² - 7x + 2

• (x - 1) (3x + 2)
• (x - 2) (3x -1)
• (x - 1) (3x - 2)
• (x + 2) (3x + 1)

Write the polynomial in standard form given the following zeros. x = -2, 1, 4

• f(x) = (x+2)(x-1)(x-4)

• f(x) =x³ - 3x² - 6x + 8

• f(x) = x³ + 8

• f(x) = x³ - 3x² + 8

Decide if (x-3) is a factor of 3x³+10x²-x-12

• Yes, it is a factor!
