Find all of the zeros of the equations below. show all of your work. 4) x3 – 5x2 + 6x = 0 5) x4 – 8x2 – 9 = 0 6) 5x3 – 5x = 0

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

it is 10.6 according to my calculations
