Polynomial Algebra Review

A square has a side length of x + 4. What is the area of the square?

• x² + 16

• x² + 8x + 16

• 4x + 16

• x² - 8x + 16

Find the area of the shaded region:

• 66x³ + 120x²

• 80x² - 24x

• 66x³ + 40x² + 24x

• 66x³ + 40x² - 24x

Identify the zeros:

• x=-2, x=-1, x=0

• x=-2, x=0

• x=-1, x=0, x=2

• x=-2, x=0, x=1

• The function has an Even degree
• The function has a Negative leading coefficient

• The function has an Odd degree
• The function has 3 real zeros

f(x)=(x+4)(x-3)(x-2)

List the zeros for this function.

• x= -4, x=3, x= -2

• x= -4, x=3, x=2

• x= -4, x=-3, x=2

• x=4, x= -3, x= -2

Find f(2)
f(x) = x³ - 5x² - 25x + 125

• 103

• 61

• 63

• 103

If x²+3x+7 is divided by x+2, then what is the remainder?

• 0

• -3

• 9

• 5

What is the leading coefficient?

• Positive

• Negative
