Answer :
The answer of the following subtraction is 5[tex]a^{2} -2b^{2} +28ab[/tex]
Step-by-step explanation:
As per the question the equation will be
[tex](1+8a^{2}+16ab+2b^{2} ) - (2+3a^{2} -12ab+4b^{2} )[/tex]
To find the subtraction,
The steps are as follow
=[tex]1+8a^{2} +16ab+2b^{2} - 2 -3a^{2} +12ab-4b^{2}[/tex]
=1-2 + [tex]8a^{2} -3a^{2} +2b^{2} -4b^{2} +16ab+12ab[/tex]
[ we took the variables with same power together]
=5[tex]a^{2} -2b^{2} +28ab[/tex]
Hope it helps you.
