Multiply Binomials Calculator


Calculator used in multiplication of two binomials using FOIL method, where FOIL stand for F=First, O=Outer, I=Inner and L=Last. It has following steps with the binomial expression (ax + b)(ax +b):
First: We take the first term from each binomial and multiply them together, means ax and ax = a2x2
Outer: we take the outer or outside terms of the two binomials, means ax and b = abx.
Inner: we take the inner or insider terms of the two binomials, means b and ax = abx. Now we can combine the outer and inner terms, since they are like terms. Therefore this will be 2abx.
Last: we take the last terms of the two binomials, means b and b = b2.
Add all the terms up, from this binomial expression, we get the end product of a2x2 + 2abx + b2.
