Question

a^2b^2-a^2-b^2+1 factorize plz explain it briefly​

Answer 1

a²b²-a²-b²+1

a²(b²-1)-1(b²-1)....we wrote -1 cause...-1*-1=1 which is it's original value.... apart from this....if we would have written +1 so +1*-1= -1... which isn't it's orginal value

hence ans...

= (a²-1)(b²-1) ans....

check... expand it

a²b²-b²-a²+1 ans.......is absolutely correct

Answer 2

Step-by-step explanation:

a^2b^2 -a^2-b^2 +1
