Foiling Binomials: A Step-by-Step Information

Foiling is a well-liked algebraic approach used to multiply two binomials (two polynomials with two phrases). This method is also known as the “FOIL” methodology, an acronym for First, Outer, Interior, Final. On this information, we’ll clarify the best way to use the FOIL methodology to multiply two binomials of the shape (X B Hh)(X B Hh). Step one is to take the First time period of every binomial and multiply them collectively. On this case, that might be X B multiplied by X B, which is the same as X²B².

The subsequent step is to multiply the Outer phrases collectively. This implies multiplying X B from the primary binomial with Hh from the second binomial, which is the same as XBHh. The Interior phrases are multiplied subsequent. This implies multiplying B from the primary binomial with Hh from the second binomial, which is the same as BHh. Lastly, the Final phrases are multiplied collectively. This implies multiplying B from the primary binomial with B from the second binomial, which is the same as B².
