Hello!

Answer:

\boxed{\boxed{\bf THEME:\:EQUATIONS\:\:WITH\:\:PARENTHESIS}}

Es\:\:-4x^2+6x+4

Step-by-step explanation:

(x^2 + 5x + 2) - (5x^2 - x - 2)

◈We remove the parentheses:

x^2+5x+2-5x^2+x+2

◈We subtract "x²" and "5x²":

-4x^2+5x+x+2+2

◈We add up "5x" and "x":

4x^2+6x+2+2

◈We add up "2" and "2":

-4x^2+6x+4

Answer:

{ \tt{( {x}^{2} + 5x + 2) - (5 {x}^{2} - x - 2)  }} \\  = { \tt{(1 - 5) {x}^{2}  + (5 + 1)x + (2 + 2)}} \\  = { \tt{ - 4 {x}^{2} + 6x + 4 }} \\  = { \tt{ - 2(2 {x}^{2} - 3x - 2) }}
