Algebra: Chapter 5, Lesson 11, page 249 (day 2). Multiplying Polynomials To multiply a monomial and a polynomial: multiply each term of the polynomial by the monomial There are 3 techniques to multiply binomials: FOIL (FIRST, OUTSIDE, INSIDE, LAST – … Continue reading →

Algebra: Chapter 5, Lesson 11, page 249. Multiplying Polynomials To multiply a monomial and a polynomial: multiply each term of the polynomial by the monomial There are 3 techniques to multiply binomials: FOIL (FIRST, OUTSIDE, INSIDE, LAST – or its … Continue reading →

Algebra: Chapter 5, Lesson 10, page 245. Multiplying Binomials: Special Products We can use the FOIL or BOX methods to multiply binomials. There are however, 3 special cases that if you recognize them, will save you some work: `(A+B)(A-B)=A^2−B^2` `(A+B)(A+B)=A^2+B^2+2AB` … Continue reading →

Algebra: Chapter 5, Lesson 9, page 240. Multiplication of Monomials and Binomials If we multiply a monomial and a binomial, all we have to do is DISTRIBUTE the monomial through the binomial, pretty simple to do (REMEMBER: the CRAZY arrows … Continue reading →

Algebra: Chapter 5, Lesson 8, page 236. Subtraction of Polynomials We do just like the addition of polynomials, except for subtraction, we (remember way back to subtracting with negative numbers) add the opposite. The other thing we have to remember … Continue reading →

Algebra: Chapter 5, Lesson 7, page 231. Addition of Polynomials When we add polynomials, it can be easier if we order them in descending order for one of the variables. We can add polynomials in 2 ways: Horizontally – scan … Continue reading →

Algebra: Chapter 5, Lesson 6, page 226. We can write polynomials is ascending or descending order. For descending order, the term with the greatest exponent for our variable of interest is first, the term with the next greatest exponent for … Continue reading →

Algebra: Chapter 5, Lesson 5, page 221 Polynomials Polynomials is the catch term for monomials put together with `+` or `–` signs. Polynomials with just 1 term are called “monomials”, with 2 terms they are called “binomials”, with 3 terms, … Continue reading →

Algebra: Chapter 5, Lesson 4, page 217. Scientific Notation We can write numbers as the product of a power of 10 and a number greater than 1 but less than 10 (9.9999…. to be exact). Standard notation is the stuff … Continue reading →
