(x-6)(x+ 3) =

a. x^2 - 18
b. x^2 - 3x - 18
c. x^2 + 3x -18
d. x2 + 9x - 18

x^2 - 3x - 18

Step-by-step explanation:

Just follow in terms of FOIL

First, outer, inner, last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.

x^2 - 3x - 18.

Step-by-step explanation:

step1- expand the brackets
