Answer:


(x^2+8x+8)/(2x+4)\\\\

Explanation:

Simplify:


(3x + 4)/(x +2)+(x^2+2x)/(2x+ 4)

Multiply the denominator and the numerator of the first term by 2,


=(2*(3x +4))/(2*(x+ 2))+(x^2+2x)/(2x+4)\\\\\\=(2*3x+2*8)/(2*x +2*2)+(x^2+2x)/(2x+4)\\\\\\=(6x+8)/(2x+4)+(x^2+2x)/(2x+4)


\sf = (6x+8+x^2+2x)/(2x+4)\\\\\text{\bf Combine like terms,}\\\\=(x^2+8x+8)/(2x+4)\\\\
