When 9 is subtracted from the square of a number, the result is 8 times the number. find the negative soulution. plz fast

The negative solution  k = -1 is the desired solution.

Step-by-step explanation:

Let the given number = k

So, according to the question:

or,

Now, solving this quadratic equation, we get

or, k ( k-9) + 1 (k-9) = 0

⇒( k-9)(k+1)  = 0

or, ( k-9)  = 0 , or (k+1)  = 0

⇒  k  = 9  or  k  = -1

Since we only want the negative solution , the k = -1 is the desired solution.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

8 2/3 is the answer

step-by-step explanation: just use a calculator
