Question

3 times a number is 54 less than the square of that number

Answer 1

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

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

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

n = 9 , -6

hope this helps

Answer 2

3x = x^2 - 54
x^2 - 3x - 54 = 0
(x - 9)(x + 6) = 0
The answer is 9 or -6
