Hii mate,✌✌

your answer is ⬇️

=》

$(2bc) {}^{2} - ( - a + b + c)$

Using

$a { }^{2} - b {}^{2} = (a - b)(a + b)$

${2bc - ( - a + b + c)} \times {2bc + (a + b + c)}$

$(2bc + a - b - c) \times {2bc + ( - a + b + c$

$(2bc + a - b - c) \times (2bc - a + b + c)$

HENCE , YOUR ANSWER IS

$(2bc + a - b - c) \times (2bc - a + b + c)$
