Step-by-step explanation:

$\tt{4 {x}^{2} + 7x - 3 - (2 {x}^{2} + 3x - 1)}$

While subtracting , the sign of each and every term of second expression changes.

⤏ $\tt{4 {x}^{2} + 7x - 3 - 2 {x}^{2} - 3x + 1}$

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⤏ $\tt{4 {x}^{2} - 2 {x}^{2} + 7x - 3x - 3 + 1}$

⤏ $\tt{2 {x}^{2} + 4x - 2}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{ \: 2 {x}^{2} + 4x - 2}}}}}}}$

Hope I helped ! ツ

Have a wonderful day / night ! ♡
