Answer 1

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\sf{\underline{\underline{\large{\bold{Answer:-}}}}}$

$\: \: \ggg \rm{ {x}^{2} + 7x + 10 = 0}$

$\: \ggg \rm{ {x}^{2} + 5x + 2x + 10 = 0}$

$\: \: \ggg \rm{x(x + 5) + 2(x + 5) = 0}$

$\: \ggg \rm{(x + 5)(x + 2) = 0}$

$\: \: \ggg \rm{(x + 5) = 0 \: and \: (x + 2) = 0}$

$\: \: \ggg \rm{x = - 5 \: and \: x = - 2 \: }$

$\: \bullet \underline{ \bf { x = - 5 \: and \: x = - 2\: is \: the \: solution }}$

Answer 2

Answer:

x=-5 or x=-2

Step-by-step explanation:

x2+7x+10=0

x2+5x+2x+10=0

x(x+5)+2(x+5)=0

(x+5)(x+2)

x=-5 or x=-2
