Question

Factorise each of the following:

27-125a^3-135a+125a^2

-_-

Jaldi ..

Answer 1

Answer:

Step-by-step explanation:

(a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3

(3-5a)^3 = 27 - 3(9)(5a) + 3(3)(25a^2) - 125a^3

27- 135a+225a^2-125a^3

Answer 2

Answer:

Answer:

$27 - {125a}^{3} - 135a + {225a}^{2}$

$= {3}^{3} - {5a}^{3} - 45(3 - 5a)$

$= {3}^{3} - {5a}^{3} -( 3 \times 3 \times 5a)(3 - 5a)$

$= {3 - 5a}^{3} = (3 - 5a)(3 - 5a)(3 - 5a)$

here your answer mate✌
