(2x²+7x-3)/(2x+5)=(2x²+5x+2x-3)/(2x+5)
=x(2x+5)/(2x+5)+ (2x+5-5-3)/(2x+5)
=(x+1)/(2x+5)-8/(2x+5)
==> 2x²+7x-3=(x+1)(2x+5)-8
Quotient=x+1 remainder=-8

Answer:

x+1 and remainder is -8

Explanation:

Given that an algebraic expression


2x^2+7x-3 is divided by
2x+5

We have to find the quotient and remainder.


2x+5) 2x^2+7x-3(x+1\\\\           2x^2+5x\\           --------------\\                     2x-3\\\\                      2x+5\\            ----------------\\                         -8 =R

Quotient is x+1 and remainder is -8
