Hi is my answer correct? tama poba ung -9 + +2 ko po is -11 iplus poba hindi poba Sya iminus?

$\huge \tt{ANSWER:}$

$\largenderline{\rm\color {orange}{ \large{ \tt{ {x}^{2} - 4x - 8 \:}}}}$

===========================================

$\huge \tt{SOLUTION:}$

Apply rule : (a) = a

$\large{ \tt{ ( {x}^{2} - 3x - 9) = {x}^{2} - 3x - 9 \:}}$

$\green{⊱┈────────────────────┈⊰}$

Apply the Distributive Law : -( a - b ) = -a +

$\large{ \tt{ - (x - 1) = - x + 1\:}}$

$\green{⊱┈────────────────────┈⊰}$

Group Like Terms :

$\large{ \tt{ {x}^{2} - 3x - x - 9 + 1\:}}$

$\green{⊱┈────────────────────┈⊰}$

Add the numbers : -9 + 1 = -8

$\large{ \tt{ { x}^{2} - 3x - x - 8 \:}}$

$\green{⊱┈────────────────────┈⊰}$

And lastly,add similar elements:

3x - x = -4x

And you will get the answer.
