Answer 2

Answer:

(4m-7m)[16m²+28mn+49n² ]. Explanation: We know the algebraic identity: a³-b³ = (a-b)(a²+ab+b²). Given. 64m³ - 343n³. = (4m)³ ...

Step-by-step explanation:

A factorised answer will always contain a set of brackets. To factorise an expression fully, take out the highest common factor (HCF) of all the terms. For example, is the HCF of 4 x 2 and as 2 is the biggest number that will divide into 4 and 6 and is the biggest variable that will divide into and .
