Question

The square of 9 less than a number is 3 less than the number. What is the number?

Answer 1

You have to create the equation.
The number is a variable (x).
$\sqrt{9} < x = 3 < x$

Answer 2

Answer:

The number is 12 or 7.

Step-by-step explanation:

According to question,

The square of 9 less than a number is 3 less than the number.

i.e. $(x - 9)^2 = x - 3$

Solving the equation,

$x^2 - 18x + 81= x - 3$

$x^2 - 19x + 84 = 0$

$(x - 12)(x - 7) = 0$

$(x - 12)=0,(x - 7) = 0$

$x=12,7$

Therefore, The number is 12 or 7.
