`((2x^(2) - 4)/(3x^(2) + 7))`

Find each of the following products: (i) (4x - 7y) (4x - 7y) (ii) (3x^(2) - 4y^(2)) (3x^(2) - 4y^(2))

lim _ ( xto infty ) ( 3x^(2) -4x + 5)/( 7x^(2) + 2x +3)

Multiply (2x^(3) - 5x^(2) - x + 7) by (3 - 2x + 4x^(2))

If x in R - {0} then minimum possible value of the expression (1)/(7)[(3x^(2)+(4)/(3x^(2))+1)^(2)-2(3x^(2)+(4)/(3x^(2)))+4]

Differentiate the following w.r.tx (i) (5x^(2) +6)(2 x^(3) +4 ) (ii) sqrtx (x^(2) +7) (iii) (x^(2) +3 )(x^(4) - 9)

((6x^(4)+8x^(3)+27x^(2)+7)/(3x^(2)+4x+1))

((5x^(2) + 6x+ 7))/((2x^(2) + 3x +4))

Multiply: 2x^(2)-4x+5)by(x^(2)+3x-7)

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)
