Question

factorize it ????? urgent I will mark them as brain list​

Answer 1

$27x^{3} - 135x^{2} + 225x - 125 \\= (3x)^{3} + 3\times (3x)^{2} \times (-5) + 3\times (3x) \times (-5)^{2} + (-5)^{3} \\= [ 3x+(-5)]^{3}$

$\boxed { \pink { a^{3} + 3a^{2}b + 3ab^{2} + b^{3} = (a+b)^{3} }}$

$= ( 3x - 5 )^{3} \\= (3x-5)(3x-5)(3x-5)$

Therefore.,

$\red {27x^{3} - 135x^{2} + 225x - 125}\\\green {=(3x-5)(3x-5)(3x-5)}$

Answer 2

Answer:

Step-by-step explanation:

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

=(3x)^3-3*(3x)^2*5+3*(3x)*(5^2)-5^3

this is in the form of a^3-3a^2b+3ab^2-b^3=(a-b)^3

(3x-5)^3
