Three less than a number squared can be expressed mathematically as ( x^2 - 3 ), where ( x ) represents the number. This formula indicates that you first square the number and then subtract three from the result. For example, if the number is 4, then three less than the number squared would be ( 4^2 - 3 = 16 - 3 = 13 ).
two less than three times a number is 28
Let the number be x Then its square is x^2 3 less than the square of a number is x^2-3 (or x square minus three)
Five (5) more than (+) three times a number (3x) is (=) five times the number (5x) less (-) three (3) 5 + 3x = 5x - 3 x = 4
