Factoring trinomials worksheet

Factoring trinomials worksheet (solved examples)  Factorise  the  following  Quadratic trinomials    by spiliting  the middle terms.   We know, in order to factorise the expression ax2 + bx + c, we have to find two numbers p and q, such that p + q = b and p × q = ac. Example 1: Factorise  . Solution. Find two factors p and q such that p+q=-7 and pq =12 . Take p=-3 and q=-4  then 12= -3 x (-4) and -3-4=-7 . Therefore  = = = = Example 2: Obtain the factors of . Solution.  = = = Example 3: Find …

Factoring Polynomials Formula and Factoring Polynomials Worksheet with Answers

Factoring Polynomials Formula and Factoring Polynomials Worksheet with Answers What is Factorisation? Representation of an algebraic expression  (  polynomials  )as the product of two or more expressions is called factorisation. Each such expression is called a factor of the given algebraic expression.  These factors may be numbers, algebraic variables or algebraic expressions. When  the factors  of the polynomial are multiplied together, you will get  the original polynomial. Methods of Factoring Polynomials There are a certain number of methods by which we can factorise polynomials. Let us discuss these methods. (i) Method of common factors The first method for factoring polynomials will be …
