Expanding (x+1)(x+7)

This expression represents the multiplication of two binomials: (x+1) and (x+7). To find the answer, we can use the FOIL method, which stands for First, Outer, Inner, Last.

Here's how it works:

1. First: Multiply the first terms of each binomial: x * x = x²
2. Outer: Multiply the outer terms of the binomials: x * 7 = 7x
3. Inner: Multiply the inner terms of the binomials: 1 * x = x
4. Last: Multiply the last terms of each binomial: 1 * 7 = 7

Now, we combine all the terms:

x² + 7x + x + 7

Finally, we simplify by combining like terms:

x² + 8x + 7

Therefore, the expanded form of (x+1)(x+7) is x² + 8x + 7.
