Step-by-step explanation:
[tex] \tt{4 {x}^{2} + 7x - 3 - (2 {x}^{2} + 3x - 1)}[/tex]
While subtracting , the sign of each and every term of second expression changes.
⤏ [tex] \tt{4 {x}^{2} + 7x - 3 - 2 {x}^{2} - 3x + 1}[/tex]
Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.
⤏ [tex] \tt{4 {x}^{2} - 2 {x}^{2} + 7x - 3x - 3 + 1}[/tex]
⤏ [tex] \tt{2 {x}^{2} + 4x - 2}[/tex]
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{ \: 2 {x}^{2} + 4x - 2}}}}}}}[/tex]
Hope I helped ! ツ
