Question

xcube +27 factories by using identities​

Answer 1

Answer:(X+3) (x^2-3x+9)

Step-by-step explanation:

x^3+27 is also written as x^3+3^3 in the simplest form

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

Substituting

(x+3) (x^2-3x+3^2)

i.e (X+3) (x^2-3x+9)

Answer 2

HeYa❤️...

Used Identity:

$(x + y) {}^{3} = x {}^{3} + y {}^{2} + 3xy(x + y)$

Solution:

$= x {}^{3} + 27 \\ \\ = (x + 3) {}^{3} \\ \\ = (x) {}^{3} + (3) {}^{3} + 3(x)(3) (x + 3) \\ \\ = x {}^{3} + 27 + 9x(x + 3) \\ \\ = x {}^{3} + 27 + 9x {}^{2} + 27x$
