The highest common factor here is 5, so we want to take 5 out of the equation first When we do this, we get 5(4x^2 1) This expression is not yet fully factorised as (4x^2 1) can be split into two more brackets because it is a difference of two squares Both 4 and 1 are square numbers so this can factorise into (2x1)(2x1)Example 9 Factorise x 2 5 x 6 Solution If we compare the RHS of Identity (IV) with x 2 5 x 6, we find ab = 6, and a b = 5 From this, we must obtain a and b (2x) 2 = 2x 2 (2x) 2 = 4x 2 Remember, when you square a monomial, the numericalFactorise x^3 3x^2 9x 5 Get the answer to this question and access a vast question bank that is tailored for students UhOh!

Using these numbers, I can split the middle −13x term into the two terms −9x and −4x, and then I can factor in pairs 6 x2 − 13x 6 = 6 x2 − 9x − 4x 6 = 3 x (2 x − 3) − 2 (2 x − 3) = (2x − 3) (3x − 2) The factoring method in the last two examples aboveLet f (x) = 2x^3 5x^2–19x 42 Try x= — 1 or x= 2 By remainder theorem if remainder of polynomial is 0 for that particular value x=a then we can say that (xa ) is a FACTOR of f (x) Put x=2 in f (x) f (2) = =0 (x2) is afactor of f (x) Dividing f (x) by (x2) long method or synthetic method we get (2x^2x21)
