Question

64a3-27b3+108ab2 -144a2​

Answer 1

Answer:

Step-by-step explanation:

According to the equation,

(a +b) ³ =a ³ +b³  +3b (a +b)

we get,  using the formula we can it write it as

64a ³  −27b³    −144a² b+108ab²   =(4a) ³ −(3b)  ³−3(4a)(3b)(4a−3b)

We can write it as  

64a³   −27b³  −144a²b + 108 ab² = ( 4a -3b)²

64 a ³ - 27b³ - 144a²b + 108ab² = (4a-3b) (4a-3b) (4a-3b)
