Explanation:
Definitions
Integer: A whole number that can be positive, negative, or zero.
Consecutive Integers: Integers that follow each other continuously in the order from smallest to largest.
Product: The result of multiplying two of more values together.
Let x be the first integer.
Therefore, to find the consecutive integers, add 1 to each term:
- x
- x + 1
- (x + 1) + 1 = x + 2
Therefore, the product of the first three consecutive integers is:
![\begin{aligned}x(x+1)(x+2) & = (x \cdot x+x \cdot 1)(x+2)\\& = (x^2+x)(x+2)\\ & = x^2 \cdot x+x^2 \cdot 2+x \cdot x+x \cdot 2\\& = x^3+2x^2+x^2+2x\\& = x^3+3x^2+2x\end{aligned}](https://img.qammunity.org/2023/formulas/mathematics/college/7pw0f80ipg4ds79h5svbmxeb0xxvfl0ctr.png)
