Given - an equation in it's general form

To do - convert the given equation into a form that is easy to solve

Given equation -

$\bold{(x + 2) {}^{2} + 4(x + 2) - 5 = 0} \\$

solve the parenthesis so as to obtain simpler terms

$\bold{\implies \: ( x {}^{2} + 4x + 4 ) + 4x + 8 - 5 = 0}\\$

solve the like terms and you'll obtain the required equation !

$\bold{\implies \: x {}^{2} + 8x - 7 = 0}$
