We not need any hints, directly the answer:-
x²+3x²-10
=----------------
x²+5
x²+(5-2)x²-10
=----------------------
x²+5
x²+5x²-2x²-10
=-----------------------
x²+5
x²(1+5)-2(x²+5)
=--------------------------------
x²+5
6x² - 2(x²-5)
=--------------------------
(x²+5)
= 6x² - 2
=> 2(3x² - 1) (Answer)
