1. ## solve this

(2x+1)(2x+3)(x+3)(x+4)=300
problem is that i could not conclude this problem

Expand the left hand side and re-arrange the equation into the form

quartic = 0.

The quartic factorises as $(x - 1)(2x + 11)(2x^2 + 9x+24)$.

The details are left for you to do. Please show your full working and where you get stuck if you need more help.

3. i re-arranged the lhs like (2x+1)(x+4) (2x+3)(x+3)
and in process i get common terms that i assume as a that will become as (a+2)( a+3)

This makes no sense. Go back and read what I suggested that you do.
