Question

(x+2)^3 - (3)^3 resolve in factors

Answer 1

Step-by-step explanation:

$\sf \: ( {x + 2})^{3} - {3}^{3}$

(x+2)³is like (a+b)³

$\sf \: {( \times + y)}^{3} = {x}^{3} + {y}^{3} + 3xy(x + y)$

$\sf \: {x}^{3} + {2}^{3} + 3 \times x \times2(x + 2)$

$\sf \: {x}^{3} + 8 + 3x(2x + 4)$

$\sf \: {x}^{3} + {6x}^{2} + 12x-19$

Then we have split into irrational roots, and we get the answer...
