Question

A polynomial p has zeros when x=5, x=-1 and x=-1/4

Answer 1

Answer:

p(x) = (5x - 1) (x + 4) (x - 2)

Answer 2

Option B: p(x) = (x - 5)(x + 1)(4x + 1)

You have zeroes when each set of parenthesis equals zero.

x - 5 = 0
Add 5
x = 5

x + 1 = 0
Subtract 1
x = -1

4x + 1 = 0
Subtract 1
4x = -1
Divide 4
x = -1/4
