Question

If i subtract my number, then square the result, I get the same answer as if i square my number, then subtract 20 from the result

Answer 1

The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.

What is an Algebra equation?

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.

Let the number be x.

If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².

And if I square my number that is x² then subtract 20 from the result that is x² - 20.

Both the result are the same then we have

         (x - 20)² = x² - 20

x² - 20x + 100 = x² - 20

  -20x + 100 = -20

                  x = 6

My number is 6
