FOIL Multiplying Polynomials
Terms • Polynomial – • a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients • Binomial – • A polynomial with 2 terms.
What does FOIL Mean • F • First • O • Outer • I • Inner • L • Last
Practice - • (k + 7 )( k – 4) • What are the “Firsts”? • What are the “Outers”? • What are the “Inners”? • What are the “Lasts”? • Hint: Always Multiply, Until you combine like terms.
One more time… • (2k + 9)(3k - 4)
