Factoring 196m225n2196m^2 - 25n^2

To factor 196m225n2196m^2 - 25n^2, recognize it as a difference of squares: (14m)2(5n)2(14m)^2 - (5n)^2. Applying the pattern a2b2=(ab)(a+b)a^2 - b^2 = (a - b)(a + b) with a=14ma = 14m and b=5nb = 5n results in the product of conjugates (14m5n)(14m+5n)(14m - 5n)(14m + 5n). Checking by multiplying confirms (14m5n)(14m+5n)=196m225n2(14m - 5n)(14m + 5n) = 196m^2 - 25n^2.
