Question

X + 3 whole cube + x minus 3 whole cube​

Answer 1

Step-by-step explanation:

put identity of a^3+b^3 in this and you easily find the answer

Answer 2

Answer:

Concept: put the formulae of $a^{2}+b^{2}$

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

TO FIND: the solution of the given question

Step-by-step explanation:

$(x+3)^{2} + (x-3)^{2}$

now, by putting the $a^{2}+b^{2}$ in the question,

$(x+3)+(x-3)$   {$(x+3)^{2} +x^{2} -(x+3)(x-3)$}

so, $2x$ { $x^{2} +9+6x+x^{2} +9-6x-(x^{2} +3x-3x-9)$}

so, $2x$  {$x^{2} +27$}

so, $2^{3}+54$

∴the answer is $2^{3}+54$.
