Answer 2

Hey friend,
Here is the answer you were looking for:
${(3 {a}^{2} + 9) }^{2} \\ \\ using \: the \: identity \\ {(a + b)}^{2} = {a}^{2} + {a}^{2} + 2ab \\ \\ = {(3 {a}^{2}) }^{2} + {(9)}^{2} + 2 \times 3 {a}^{2} \times 9 \\ \\ = 9 {a}^{4} + 81 + 54 {a}^{2} \\ \\ = 81 +54 {a}^{2} + 9 {a}^{4}$

Hope this helps!!!
