Question

Add a+b+ab ; b-c+bc ; c+a+ac

Answer 1

QUESTION :

Add a+b+ab ; b-c+bc ; c+a+ac

ANSWER :

We have to add the following terms

a+b+ab..........1

b-c+bc............2

c+a+ac..........3

so by adding 1 , 2 , and 3

we get,

a+b+ab + b-c+bc + c+a+ac

= 2a +2b +ab+bc+ac

= a(b+c+2)+b(c+2)

= ab+a(c+2)+b(c+2)

=(a+b)(c+2)+(ab)

= 2a+2b+ab+bc+ac

NOTE :

while solving such questions it is preferable to put the answer in the simplest form

and try to write the answer in the simple way so the examiner is not able to cut your marks
