Zeros of Polynomials Test

Find the zeros of the polynomial.
f(x) = (x-5)(2x+3)(7x-4)(x+6)

• x = 5, (2/3), 6, (7/4)
• x= -5, (3/2), (-4/7), 6
• x= 5, (-3/2), (4/7), -6
• x= 6, 5, -2/3, -4/7

What are the zeros of the function?

• 4,1
• 3,1,-2,-5
• -3, -1, 2, 5
• -2,4

What do "zeros" represent?

• something a polynomial can not be.

• the place that the polynomial crosses the x axis/ the x value that makes the whole equation equal to zero

• the place that the polynomial crosses the y axis/ the y value where x=0

• the number zero

To find zeroes of polynomials, we...

• say x=0

• make pancakes

• ask NASA

• set factors equal to zero

• x=-5

• x=-4 x=1

• x=1

• x=1 and x=-5

• x=-1 and x=5

The degree of the function is...

• the size of it

• the number of terms

• the greatest exponent on the variable

• a BS in mathematics

The degree of a function is always equal to...

• the number of petals on a daisy

• the number of factors

• one less than the number of zeros

• the number of terms in the polynomial
