Answer 2

Answer:

$\huge{\boxed{ \red{Answer }}}$

${ x^2} \:+\:10x\:={ 12^2}$

${ x^2} \:+\:10x\:={144 }$

${ x^2} \:+\:10x\:-144\:=0$

$since\:it\:is\:quadratic\:equation$

$it\:can \:be \:factorised$

$\green{ on\:factorisation}$

${ x^2}+18x\:-\:8x\:-\:144\:=0$

$x(x\:+\:18) \:-\:8(x\:+\:18)\:=0$

$(x\:-\:8)(x\:+\:18)\:=0$

$here\: are\: two\: values\: of \:x$

$x\:=\:8$

$\huge\purple{and }$

$x\:=\: -18$
