first number = x second number = x + 1 third number = x + 2 Set that expression = 504, and you're ready to solve. x(x+1)(x+2) = 504 Multiplying the three factors in our expression, you should arrive at: x³ + 3 x² + 2x x³ + 3 x² + 2x = 504 x³ + 3 x² + 2x - 504 = 0 So we have (x- 4)(x² + 7x + 30) = 0

But if we stick with whole numbers, the three consecutive numbers would be 7, 8, and 9. The equation would look like this: x + (x+1) + (x+2) = 504 Combining like terms, you would have: 3x + 3 = 504 After solving this, I get x = 167. This does NOT answer the question posed because the problem asked for the second number. Remember we said that the first number was represented by x. Recall that the expression representing the second number is x + 1.

Answer:
7, 8 and 9
Step-by-step explanation:
Hirap eh explain pero correct answer yan
second number = x + 1
third number = x + 2
Set that expression = 504, and you're ready to solve.
x(x+1)(x+2) = 504
Multiplying the three factors in our expression,
you should arrive at: x³ + 3 x² + 2x
x³ + 3 x² + 2x = 504
x³ + 3 x² + 2x - 504 = 0
So we have (x- 4)(x² + 7x + 30) = 0
The equation would look like this:
x + (x+1) + (x+2) = 504
Combining like terms, you would have: 3x + 3 = 504
After solving this, I get x = 167. This does NOT answer the question posed because the problem asked for the second number. Remember we said that the first number was represented by x. Recall that the expression representing the second number is x + 1.
