Write the quadratic equation in standard form.(x  - 3)  2  = 0a. x  2  + 9 = 0b. x  2  + 6x + 9 = 0c. x  2  - 6x + 9 = 0

Therefore, c)  x²- 6x. +9 .

Step-by-step explanation:

Given: (x - 3) ² = 0

To find: Write the quadratic equation in standard form.

Solution: We have given that (x - 3) ² = 0

  By the  (a- b) ²=a²+ b²- 2ab

Here a=  x and b= 3

(x- 3) ²= x²+ 3²- 2* x * 3

(x- 3) ²=  x²+9 - 6x.

Therefore, c)  x²- 6x. +9 .

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
