[tex]\boxed{-49x\ +\ 13}[/tex]

[ Explanation ]

  • Simplify: (3 - 13x - 7 · 2) - (5 · 2 + 12x - 10)

----------------------------------

  • Remove Parenthesis

3 - 13x - 7x · 2 - (5 · 2 + 12x - 10)

7x · 2 = 14x

-(5x · 2 + 12x - 10) = -(22x - 10)

3 - 13x - 14x - (22x - 10)

-(22x - 10): -22x + 10

3 - 13x - 14x - 22x + 10: -49x + 13

[tex]\boxed{[ \ Eclipsed \ ]}[/tex]

-49x + 13

Answer:  

-12x2 − 25x + 13

Step-by-step explanation:

(3 -13x -7x2)-(5x2 +12x -10)   multiply the entire second term by negative one

3 - 13x -7x^2 -5x^2 -12x +10   combine like terms
