$\sf {a}^{2} = {3a}^{2} \\ \\ \sf \: Subtract \: 3a" \: from \: both \: sides \\ \sf \dashrightarrow{a}^{2} - {3a}^{2} = {3a}^{2} - {3a}^{2} \\ \\ \sf \: Simplify \\\sf \dashrightarrow { - 2a}^{2} = 0 \\ \\ \sf \: Divide \: both \: sides \: by \: - 2 \\ \sf \dashrightarrow \frac{ { - 2a}^{2} }{ - 2} = \frac{0}{ - 2} \\ \\ \sf \: Simplify \\\sf \dashrightarrow a^{2}=0 \\ \\ \sf \: Apply \: rule \: {x}^{n} = 0 \implies X = 0\\ \sf \dashrightarrow \red{a=0}$
