Question

factorise 2(x + 2y) square. -5(x +2y) + 2​

Answer 1

Step-by-step explanation:

2(x+2y)²-5(x+2y)+2

let (a+2y)=a. then,

2a²-5a+2

2a²-a-4a+2. ( by splitting middle term)

a(2a-1)-2(2a-1)

(2a-1)(a-2)

Now put a=x+2y

{2(x+2y)}{x+2y-2}

(2x+4y-2)(x+2y-2)

Answer.

Answer 2

Answer:

Step-by-step explanation:

2(x+2y)²-5(x+2y)+2

let (a+2y)=a. then,

2a²-5a+2

2a²-a-4a+2. ( by splitting middle term)

a(2a-1)-2(2a-1)

(2a-1)(a-2)

Now put a=x+2y

{2(x+2y)}{x+2y-2}

(2x+4y-2)(x+2y-2)
