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. [tex](x - 9)^2 = x - 3[/tex]
Solving the equation,
[tex]x^2 - 18x + 81= x - 3[/tex]
[tex]x^2 - 19x + 84 = 0 [/tex]
[tex](x - 12)(x - 7) = 0 [/tex]
[tex](x - 12)=0,(x - 7) = 0 [/tex]
[tex]x=12,7 [/tex]
Therefore, The number is 12 or 7.
