please jo aata hai woh btado 3 wala pls btao baki bhi btao​

Answer 1

Step-by-step explanation:

(+2)(−2)(2+4)

{\color{#c92786}{(a+2)(a-2)(a^{2}+4)}}(a+2)(a−2)(a2+4)

(2+4)(−2)+2(2+4)(−2)

{\color{#c92786}{a(a^{2}+4)(a-2)+2(a^{2}+4)(a-2)}}a(a2+4)(a−2)+2(a2+4)(a−2)

Distribute

(2+4)(−2)+2(2+4)(−2)

{\color{#c92786}{a(a^{2}+4)(a-2)}}+2(a^{2}+4)(a-2)a(a2+4)(a−2)+2(a2+4)(a−2)

(−2)⋅3+4(−2)+2(2+4)(−2)

{\color{#c92786}{(a-2) \cdot a^{3}+4a(a-2)}}+2(a^{2}+4)(a-2)(a−2)⋅a3+4a(a−2)+2(a2+4)(a−2)

Distribute

(−2)⋅3+4(−2)+2(2+4)(−2)
