Write x2 - 2x - 3 = 0 in the form (x - a)2 = b, where a and b are integers. (x - 4)2 = 3 (x - 3)2 = 2 (x - 2)2 = 1 (x - 1)2 = 4

The correct option is 4.

Step-by-step explanation:

The given equation is

If an expression is , then to make it perfect sqaure add .

Here b=-2,to make the perfect square we need to add ,i.e, 1.

Add 4 on both the sides.

Therefore the correct option is 4.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
