Answer 1

$\red{HEY\:BUDDY!!}$

HERE'S THE ANSWER...

_____________________________

♠️ Remember , this like variables can only be added or subtracted

⏺️ Example = 2 x + 2 x = 4 x

=> 2 x^2 + 2 x + 2 x

=> 2 x^2 + 4 x

⏺️ It can't be solved future , but you can that common

♠️ ANSWER

=> 15 x - 3 x + ( 6 x^2 - 5 x )

=> 6 x^2 + 15 x - 3 x - 5 x

=> 6 x^2 + 15 x - 8 x

=> [ 6 x^2 + 7 x ] ✔️

$\bold{When \: we \: add \: or \: subtract \: any \: problem \: }$
$\bf{which \: contain \: variables}$
$\bf{then \: one \: thing \: should \:be \: noticed \: }$
$\bf{that \:both \: the \: eqaution \: have \: the}$
$\bf{same \: variable \: and \: its \: power \: }$

$\boxed{Answer \: = = > }$

$\bf{( 15x - 3x) + (6x {}^{2} - 5x)}$

$\bf{15x - 3x + 6x {}^{2} - 5x }$
$\bf{12x + 6x {}^{2} - 5x}$

$\boxed{6x {}^{2} + 7x}$
