Answer:

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

Step-by-step explanation:

$(x + 1)² + (x + 2)² - 13$

$[using \: (a+b)² = a²+2ab+b²]$

$x²+2x+1 + x² + 4x + 4 -13$

$Rearranging , we get$

$= x²+x² +2x+4x +4+1 - 13$

$= 2x² + 6x +5-13$

$= 2x²+6x -8$

$now \: dividing \: this \\ \: by \: ( \div 2), we \: get;$

$=> x²+3x -4$

$= x²+4x-x-4$

$= x(x+4) -1(x+4)$

$=(x+4) (x-1)$
