$\huge\red\star{\fcolorbox{yellow}{red}{\large{\fcolorbox{blue}{yellow}{{\fcolorbox{orange}{lime}{♛Hello♛}}}}}}\pink\star$$\fbox\pink{A}\fbox\blue{N}\fbox\purple{S}\fbox\green{W}\fbox\red{E}\fbox\orange{R}\fbox\red{♡}\fbox\green{:)}$

$(2 {a}^{2} + ab) + 3 - ab$

$= > 2(5 {}^{2} + ( - 15) + 3 - ( - 15)$

$= > 2(25 - 18 + 15)$

$= > 2(25 - 33)$

$= > 2( - 8)$

$= > - 16$
