Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{ - 2 {x}^{2} + 8x - 10}}}}[/tex]
Step-by-step explanation:
[tex] \sf{( {x}^{2} + 3x - 7) - (3 {x}^{2} - 5x + 3)}[/tex]
When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression. Also, remove the parentheses
⇒[tex] \sf{ {x}^{2} + 3x - 7 - 3 {x}^{2} + 5x - 3}[/tex]
Collect like terms
⇒[tex] \sf{ {x}^{2} - 3 {x}^{2} + 3x + 5x - 7 - 3}[/tex]
⇒[tex] \sf{ - 2 {x}^{2} + 8x - 10}[/tex]
