Answer 1

Hey mate!

Here's your answer!!

Factorize :

5) 125a³+b³+64c³-60abc

= (5a)³+(b)³+(4c)³-3(5a)(b)(4c)

= [5a+b+4c][5a²+b²+4c²-(5a)(b)-(b)(4c)-(4c)(5a)]

= [5a+b+4c][25a²+b²+16c²-5ab-4bc-20ac].



7) 1+b3+8c3-6bc

= ((1 + (b³)) + 23c³) - 6bc

= b³ - 6bc + 8c³ + 1



6) x3 + y3 + z3 – 3xyz = (x + y + z) (x2 + y2 + z2 – xy – yz – zx)

a3 + 8b3 - 64c3 + 24abc
= (a)3 + (2b)3 + (-4c)3 - 3(a)(2b)(-4c)

= (a + 2b - 4c)(a2 + 4b2 + 16c2 - 2ab + 8bc + 4ac)

∴ a3 + 8b3 - 64c3 + 24abc = (a + 2b - 4c)(a2 + 4b2 + 16c2 - 2ab + 8bc + 4ac)

Hope it helps you!
