Question

15a^2 - 28ab + 12b^2​

Answer 1

Answer:

$\huge\red\star{\fcolorbox{yellow}{red}{\large{\fcolorbox{blue}{yellow}{{\fcolorbox{orange}{lime}{♛Hello♛}}}}}}\pink\star$

$\fbox\pink{A}\fbox\blue{N}\fbox\purple{S}\fbox\green{W}\fbox\red{E}\fbox\orange{R}\fbox\red{♡}\fbox\green{:)}$

$15a {}^{2} - 28ab + 12 {b}^{2}$

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

$= > (15 - 12) {}^{2}$
