multiply (x+6)(x-1)

To expand the expression (x+6)(x-1), we can use the distributive property. We multiply each term in the first parentheses by each term in the second parentheses:

(x+6)(x-1) = x(x) + x(-1) + 6(x) + 6(-1)

Now, simplify each term:

x(x) = x^2
x(-1) = -x
6(x) = 6x
6(-1) = -6

Combine like terms:

x^2 - x + 6x - 6

Simplify further:

x^2 + 5x - 6

Thus, (x+6)(x-1) simplifies to x^2 + 5x - 6.
