Let's practice factoring with repeated use of the difference of squares formula by working through 2 examples. 81x3−16x3y4 Step 1: 81 16 1 x3 x3 81x3−16x3y4=x3(81−16y4) Step 2: (81−16y4) a2=81 b2=16y4 a
Solve it by factoring the left side and setting each factor equal to zero. (x + 5)(x – 2) = 0 x = –5, x = 2 Therefore, the possible solutions are x = –5 and x = 2. Unfortunately, there is a risk of finding an incorrect solution when solving rational equations in this ...
