Question

factorise 64m^3-343x^2​

Answer 1

you type wrong p(f).

you type wrong p(f)

because it can't be factorise

I think it is 64m^3 - 343x^3.

if this is your question so the answer of this:-

64m^3 - 343x^3

=(4m)^3 - (7x)^3

now we use Identity:-

x^3 - y^3= (x-y)(x^2+xy+y^2)

=(4m-7x)(16m^2+28mx+49x^2)
