Answer:

6

Explanation:

Let x by the unknown number.

Given:

  • Eighty-five more than the square of a number is the same as the square of the quantity that is 17 less than the number.

Therefore, the equation representing the given information is:


\boxed{x^2+85=(x-17)^2}

To solve for x, expand the right side:


\implies x^2+85=(x-17)^2


\implies x^2+85=(x-17)(x-17)


\implies x^2+85=x^2-34x+289

Subtract x² from both sides of the equation:


\implies 85=-34x+289

Add 34x to both sides:


\implies 34x+85=289

Subtract 85 from both sides:


\implies 34x=204

Divide both sides by 34:


\implies x=6

Therefore the unknown number is 6.
