Study Notes
Algebraic Expressions
- An algebraic expression combines constants and variables using mathematical operations (+, -, ×, ÷).
- A monomial has one term.
- A binomial has two terms.
- A trinomial has three terms.
Factors of Algebraic Expressions
- Factors are parts of an expression.
- Factorization is representing an expression as a product of its factors.
- Numerical coefficients of factors are multiplied to find the total coefficient.
- Factors of a monomial can be written as a product (e.g., 8a²b = 1 × 8a²b, 8a²b = 2a² × 4b, etc.)
- Common factors are factors common to two or more monomials.
- The highest common factor (H.C.F.) for monomials is the greatest common factor of the coefficients and the highest power of each variable
- Steps to find the H.C.F. of monomials:
- Find the H.C.F. of the numerical coefficients.
- Find the common variables.
- Find the highest common power of each variable.
- Multiply the H.C.F. of the coefficients and the highest common powers of the variables.
Factorisation by taking out a common factor
- Find the highest common factor (HCF) of all terms of the expression.
- Express each term of the expression as a product of HCF and the quotient obtained by dividing each term by HCF.
- Use distributive property to express the given expression as a product of HCF and the sum of the quotients.
- Terms in an algebraic expression will have common factors which can be taken out to make the expression simpler
Multiplication of a monomial and a binomial
- Multiply the monomial by each term of the binomial.
- Add or subtract the products to get the final result.
Multiplication of Binomials
- Use the distributive property twice: (a + b)(c + d) = a(c + d) + b(c + d) = ac + ad + bc + bd
Multiplication of a Binomial and a Trinomial
- Multiply each term of the binomial by each term of the trinomial.
- Combine like terms.
