Question

Factorise the following expression by perfect square method
1. 2x²-10x+8​

Answer 1

Answer:

2x^2-8x-2x+8 =0

Step-by-step explanation:

2x(x-4)-2(x-4)=0

(2x-2)(x-4)=0

Answer 2

Answer:

= 2 x 2 - 1 0 x + 8

= 2 x 2 - 2 x - 8 x + 8

= 2 x ( x - 1 ) - 8 ( x - 1 )

= ( 2 x - 8 ) ( x - 1 )
