We know that
The difference of two squares<span> is a squared number subtracted from another squared number. Every difference of squares may be factored according to the identity</span>
<span>
(A</span>²-B²)=(A+B)*(A-B)
<span>so
the answer is
</span><span>49m2 − 81n4
</span>49m2 − 81n4=(7m+9n²)*(7m-9n²)
