The positive number whose square is more then 3 will be x=2.3

<h3>What is positive number?</h3>

Positive number is defined as the number which falls in a positive quadrant.To find out the number we will form a equation according to the question.

It is given in the question that a positive number whose square is 3 more then itself.

Suppose the number is x so according to question.

x^2=x+3

x^2-x-3=0

Now by solving the quadratic equation from the formula.

x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\dfrac{-(-1)\pm\sqrt{(-1^2)-4\times 1\times-3)}}{2}

x=2.3 and  x=-1.6

Here the positive number whose square is more then 3 will be x=2.3
