Question

(a÷2-b÷2+1)^2 please tell me fast

Answer 1

Answer:

  =    (a^2 - b^2 + 1 ) / 4

Step-by-step explanation:

first  recognise that a/2 and b/2 have the same denominators hence you can solve this first

a/2 -  b/2

the answer will have the same denominator of 2 hence say a-b

: answer for this part is  (a-b)/2

now you can add the 1

this becomes (a-b+1)/2

now use the power on the entire equation :

 ( (a-b+1)/2)^2

this becomes

(a^2 - b^2 + 1^2 ) / 2^2   ( everything is put to the power of 2)

this becomes your answer

    =    (a^2 - b^2 + 1 ) / 4
