Answer :
Answer:
StartFraction 15 x cubed + 25 x squared + 5 x + 2 Over (5 x squared + 1) squared EndFraction, can be written in mathematical form as
Let y = [tex]\frac{15 x^3 + 25x^2 +5x+2}{({5x^2+1})^2}[/tex]
on expanding [tex]{({5x^2+1})^2 = 25x^4 +1 + 10x^2[/tex]
⇒ y = [tex]\frac{15 x^3 + 25x^2 +5x+2}{25x^4 +1 + 10x^2}[/tex]
there correct form of partial fraction is [tex]\frac{15 x^3 + 25x^2 +5x+2}{25x^4 +1 + 10x^2}[/tex]
