Question

64 by 125 a cube minus 96 by 25 a square + 48 by 5 minus 8 factorize​

Answer 1

Answer;

$\frac{64}{125} a {}^{3} - \frac{96}{25} a {}^{2} + \frac{48}{5} - 8 \\ \\ \frac{64a {}^{3} - 480a {}^{2} + 1200 - 1000 }{125} = 0 \\ \\ 64a {}^{3} - 480a {}^{2} + 200= 0 \\ \\ 8(8a {}^{3} - 60a {}^{2} + 25) = 0 \\ \\ 8a {}^{3} - 60a {}^{2} + 25 = 0$

Now, further it can not be factorised.
