Factoring & Solving Polynomials

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 is the factored form of the function shown?

• y = (x+3)(x-1)

• y = (x-3)(x-1)

• y = (x+3)(x+1)

• y = (x-3)(x+1)

What are the roots of the polynomial?

• -3, 0, and 3

• 0

• -2, 10, and -10

• 11, 0 and -11

How many roots does the polynomial have?

• 4

• 3

• 2

• 1

Solve  $\left(3x-7\right)\left(2x-8\right)=0$ for x

•  $x=-\frac{7}{3}$ or  $x=4$ 

•  $null$ or  $x=-4$ 

•  $x=\frac{7}{3}$ or  $x=4$  

•  $x=\frac{7}{3}$ or  $x=-4$ 

• x = - 4 and x = - 5

• x = 20 and x = - 9

• x = 4 and x = 5

• x = - 4 and x = 5
