Question

Seventy-five times an integer, minus 36, equals 21 times the square of the integer. Which equation could be used to solve for the unknown integer?

Answer 1

For this equation, we will do seventy-five times a negative integer.
-75x - 36 = -21x^2
Then, seventy-five times a negative integer we'll subtract 36, which equals -21x^2.

I believe the square of the negative integer would be -21x^2.
