`x^(2)+5x-104" `

Which of the following is a reciprocal equation of class one.1)2x^(3)+5x^(2)+5x+2=02 ) 2x^(3)+5x^(2)+5x-2=03)2x^(3)-5x^(2)+5x-2=04 none of these

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8

Factorise : (2x^(2)+5x)(2x^(2)+5x-19)+84

L_ (x rarr oo) (x ^ (2) + 5x + 2) / (2x ^ (2) -5x + 1)

lim_ (x rarr oo) (x ^ (2) + 5x + 2) / (2x ^ (2) -5x + 1)

Simplify (x-3)/(x^(2)-x-6) + (2x-1)/(2x^(2) + 5x-3) - (2x +5)/(x^(2) + 5x +6)
