The sum of a number and its square is 42. Which equation can be used to find the two numbers for which this is true?
x+x^2 = 42
Therefore x can equal -7 or 6
The equation which is the answer would be \(y=x+ x^{2}\)
x + x squared = 42. The square of the number is the number squared. BY my incredibly accurate guess and check strategy (Works most of the time), 6*6 = 36 + 6 = 42.
