Factorise 2x+y2 9x+y 5. Factorise 2(xy)^29(xy)5.  2x2 5x 2 We can Split the Middle Term of this expression to factorise it In this technique, if we have to factorise an expression like ax2 bx c, we need to think of 2 numbers such that N 1 ⋅ N 2 = 2 ⋅ 2 = 4 and N 1 N 2 = b = 5 After trying out a few numbers we get N 1 = 4 and N 2 = 1 41 = 4, and 4 1 = 5.  (ii) (x8) (x 10) (iii) (3x 4) (3x – 5) (iv) (y 2 \(\frac { 3 }{ 2 }\)) (y 2 – \(\frac { 3 }{ 2 }\)) (v) (3 – 2x) (3 2x) Solution (i) (x 4) (x 10) Using identity (iv), ie, (x a) (x b) = x 2 (a b) x ab We have, (x4) (x 10) = x 2 (4 10) x (4x 10) (∵ a = 4, b = 10) = x 2 14x40 (ii) (x 8) (x 10) Using identity (iv), ie, (x a) (x b) = x 2 (a b) x.

It's obvious that the minimum is 0 For x=2\sqrt5 and y=\sqrt5 we get a value 125 We'll prove that it's a maximal value Indeed, we need to prove that (2xy)^2\leq5(x^2y^2) or (x2y)^2\geq0.

X 2 – 2xy y 2 = (x – y) 2 Ex x 2 – 6x 9 = (x – 3) 2 If the polynomial to be factored consists of four or more terms, then try factoring by grouping.  Factorise A Polynomial By Splitting The Middle Term Example Problems With Solutions Type I Factorization of Quadratic polynomials of the form x 2 bx c (i) In order to factorize x 2 bx c we have to find numbers p and q such that p q = b and pq = c (ii) After finding p and q, we split the middle term in the quadratic as px qx and get desired factors by.

To simplify expressions first expand any brackets, next multiply or divide any terms and use the laws of indices if necessary, then collect like terms by adding or subtracting and finally rewrite the expression For example to simplify 8x 43(2x−3) 8 x 4 3 ( 2 x − 3) Expand the brackets 8x 46x −9 8 x 4 6 x − 9. 17 Factorisation (EMAG) Factorisation is the opposite process of expanding brackets For example, expanding brackets would require 2 ( x 1) to be written as 2 x 2 Factorisation would be to start with 2 x 2 and end up with 2 ( x 1) The two expressions 2 ( x 1) and 2 x 2 are equivalent;. Expand polynomial (x3)(x^35x2) GCD of x^42x^39x^246x16 with x^48x^325x^246x16;.

Answer (1 of 3) (x^{2} 2x 1 1) (y^{2} 6y 8) \rightarrow (x^{2} 2x 1) (y^{2} 23y 3^{2}) \rightarrow (x 1)^{2} (y 3)^{2} \rightarrow (x.

 Explanation Notice that when you multiply (x − y) by (x y) then the terms in xy cancel out, leaving x2 − y2 (x −y)(x y) = x2 xy −yx − y2 = x2 xy − xy −y2 = x2 −y2 In general, if you spot something in the form a2 −b2 then it can be factored as (a −b)(a b) For example 9x2 − 16y2 = (3x)2 − (4y)2 = (3x −4y. Let (xy)= p, then the equation 2(xy)2 −9(x y)−5 becomes 2p2 −9p−5Consider the expression 2p2 −9p−5 we can factorise it as follows2p2 −9p−5 = 2p2 −10pp−5 = 2p(p−5)1(p−5) = (p−5)(2p1)Now, substitute the value of p as p =(xy)(p−5)(2p1) =(xy −5)(2(x y)1) =(xy −5)(2x2y 1)Hence, 2(xy)2 −9(x y)−5. Factor 4x^2y^2 4x2 − y2 4 x 2 y 2 Rewrite 4x2 4 x 2 as (2x)2 ( 2 x) 2 (2x)2 − y2 ( 2 x) 2 y 2 Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (ab)(a−b) a 2 b 2 = ( a b) ( a b) where a = 2x a = 2 x and b = y b = y.

How to factorise x^2 6x 5 Firstly you check to see if there is a coefficient to the x 2 term, in this example there isn't so we know that both the brackets will have a single x in, (x )(x ) We also know both the signs in the brackets are positive because all the terms in the initial question are positive Now all we need to do is find two numbers that multiply together to get 5 and. Factor 9x^2 9 − x2 9 x 2 Rewrite 9 9 as 32 3 2 32 − x2 3 2 x 2 Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (ab)(a−b) a 2 b 2 = ( a b) ( a b) where a = 3 a = 3 and b = x b = x.
