3 times a number is 54 less than the square of that number. Find the positive solution.
OlgaM077 [116]

Answer:x=9

Step-by-step explanation:

To find the positive solution for this, then we will say;

Let the number be x

3x<x^2-54

x^2-3x-54<0

Then we are going to factorise

x^2-9x+6x-54=0

(x^2-9x)+(6x-54)=0

x(x-9)+6(x-9)=0

(x+6)(x-9)=0

Therefore, The positive solution for this is: x=9
