Answer 2

Answer :  The polynomial expression is, $3x^2-10x+8$

Step-by-step explanation :

According to the BODMAS rule, when the expression contains brackets open ((), {}, []) we have to first simplify the bracket followed by of (powers and roots etc.) and then we have to solve the division, multiplication, addition and subtraction from left to right order (respectively).

As we are given the expression:

$(5x^2+13x-4)-(17x^2+7x-19)+(5x-7)(3x+1)$

Now we have to simplify this expression.

$=5x^2+13x-4-17x^2-7x+19+(5x-7)(3x+1)$

$=5x^2+13x-4-17x^2-7x+19+15x^2+5x-21x-7$

$=3x^2+13x-4-7x+19+5x-21x-7$

$=3x^2-10x-4+19-7$

$=3x^2-10x+8$

Therefore, the polynomial expression is, $3x^2-10x+8$
