To multiply (x - 5)(x + 10), you can use the distributive property or the FOIL method.

Using the distributive property: (x - 5)(x + 10) = x(x) + x(10) - 5(x) - 5(10) = x^2 + 10x - 5x - 50 = x^2 + 5x - 50.

Using the FOIL method: (x - 5)(x + 10) = xx + x10 - 5x - 510 = x^2 + 10x - 5x - 50 = x^2 + 5x - 50.

So, the result of multiplying (x - 5)(x + 10) is x^2 + 5x - 50.
