Give the positive solution of x^2 – 36 = 5x.
andriy [413]
The equation given in the question is 

x^2 - 36 = 5x
x^2 - 5x - 36 = 0
x^2 - 9x + 4x - 36 = 0
x(x - 9) + 4(x - 9) = 0
(x - 9) (x + 4) = 0
From the above set we can say that x = 9 is the positive solution of the equation given in the question. I hope that this is the answer that you were looking for and it has come to your great help.

We can find the slope given two points

m = (y2-y1)/(x2-x1)

 9 = (s-0)/(9-8)

 9 = (s)/1

S = 9
