$\star\large\mathcal{\underline{\underline{PLEASE \: }}}\large\mathcal\red{\underline{\underline{F}}}\large\mathcal\green{\underline{\underline{OLL}}}\large\mathcal\pink{\underline{\underline{OW \: }}}\large\mathcal\blue{\underline{\underline{ME}}}\star$

Step-by-step explanation:

$3x²+13x+4=0$

$= 3(-4)²+13(-4)+4=0$

$= 48-52+4=0$

$= 52-52=0$

$thus , -4 \: is \: the \: solution \: of \\ \: quadratic \: equation \: because \: the \\ answer \: to \: the \: equation \: is \\ equal \: to \: zero \: which \: shows \: that \\ -4 \: is \: the \: zero \: of \: the \: given \\ quadratic \: equation.$
