Answer 1

${8a}^{2} - 27ab + {9b}^{2}$

By Middle Term Splitting

It can Be Written as

${8a}^{2} - 27ab + {9b }^{2} \\ \\ ({8a}^{2} - 3ab) - (24ab + {9b}^{2} )\\ \\ a(8a - 3b) - 3b(8a - 3b) \\ \\ (a - 3b)(8a - 3b)$

What is Middle Term Splitting

In This You have to Divide The Middle term coffecient such that on Multiplying You Got Product of First and Last Term coffecient.Like Here

When You Multiply 3×24=72 you got product of 9×8.

(a-3b)(8a-3b)
