Use completing the square to find the value to add that makes x^2 - 12x a perfect square trinomial. Then write the expression as

yarga [219]

Answer:

Step-by-step explanation:

If you want to make

$x^2-12x$

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

$(x^2-12x+36)-->(x-6)^2$

MakcuM [25]

This is a typical work problem in algebra. The approach to this is using the equation: Rt = 1, where R is the rate per person working, t is the amount of time worked by an individual. All their rates must equal to 1. The solution is as follows:

12/x + 15/x = 1
Solving for x,
x = 27 hours

So, if they work together, they can finish the work in 27 hours.
