To expand the expression (x+1)(x-7), you can use the distributive property.
First, distribute the x+1 to x and -7:
(x+1)(x-7) = x(x-7) + 1(x-7)
Multiply each term inside the parentheses by x:
= x^2 – 7x + 1(x-7)
Now, distribute the 1 to x and -7:
= x^2 – 7x + x – 7
Combine like terms:
= x^2 – 6x – 7
So, the expanded form of (x+1)(x-7) is x^2 – 6x – 7.
