It's extraneous. I know this because it leads to a straight answer. 

3x+5+15=2x+5
26x
+15
5x
=2x+5

26x+15=10x2+25x
26x
+15
−(10x2+25x)
=10x2+25x−(10x2+25x)

−10x2+x+15=0
x=−b±√b2−4ac2a

x=−(1)±√(1)2−4(−10)(15)2(−10)

x=−1±√601−20

x=120+−120√601 or x
=120+120√601

x=120+−120√601

x=120+120√601

x=120+−120√601 or x=120+120√601

Hoped I helped!
