Question

Factorize the following
(a) x2 + y2 – 2xy + 80 – 8y + 16
(b) 1 + 273​

Answer 1

Answer:

(a) 2( -xy + x - 3y + 48 ).

(b) 1( 1 + 273 )

Step-by-step explanation:

1.

$2x+2y-2xy+80-8y+16$

(Combine 2y2y and -8y−8y to get -6y−6y.)

$2x - 6y - 2xy + 80 + 16$

(Add 8080 and 1616 to get 9696.)

$2x - 6y - 2xy + 96$

(Factor out 2.)

$2( - xy + x - 3y + 48)$

2.

$1 + 273$

$1(1 + 273)$
