Question

(x + 2)^3+ (x - 2)^3​

Answer 1

You can also solve it by using a^3+b^3

Answer 2

Answer:

x(24+x^2)

Step-by-step explanation:

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

={x^3+8+6x(x+2)}+{x^3-8-6x(x-2)}

={x^3+8+6x^2+12x}+{x^3-8-6x^2+12x}

=x^3+8+6x^2+12x+x^3-8-6x^2+12x

=24x+x^3

=x(24+x^2)
