\large\bf\underline{Given:}

  • a = 2

  • b = 1

\large\bf\underline{Solving\:for:}

ㅤㅤㅤㅤㅤ\large\bf{:\implies 4(a^2 +2b^2 +2ab)-4a(a+3b)}

Substituting the values:

ㅤㅤㅤㅤㅤ\bf{⟼4(2^2 +2\times 1^2 +2\times 2\times 1) -4\times 2 (2+3\times 1 )}

ㅤㅤㅤㅤㅤ

ㅤㅤㅤㅤㅤ\bf{⟼4(4+2+4) -8\times 5}

ㅤㅤㅤㅤㅤ\bf{⟼4\times 10 - 40}

ㅤㅤㅤㅤㅤ\bf{⟼\cancel{40}-\cancel{40}}

ㅤㅤㅤㅤㅤ\bf{⟼0}

\underline{\boxed{\bf{Hence,\:your\:answer\:is\:0 }}}
