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

densk [106]

Answer:

5

Step-by-step explanation:

The height of the largest triangle = √(9 * 25) = 3 * 5 = 15

y is the square root of (25^2 + 15^2)

y = √(625 + 225)

y = √850

y = √(2 * 5*5 * 17)

y = 5 * √34
