(3x^(2)+9x+17)/(3x^(2)+9x+7)

If x is real, the maximum value of (3 x^(2)+9 x+17)/(3 x^(2)+9 x+7) is

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

State which of the following expressions are a polynomial in one variable and which are not : sqrt(7)x^(3) + (5)/(3)x^(2) - 9x + 17

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

lim_(x rarr oo) (3x^(3) + 2x^(2) - 7x + 9)/(4x^(3) + 9x -2)

The expression ((x-1)(x-2)(x^(2) - 9x + 14))/((x-7)(x^(2) - 3x + 2)) in the lowest terms is:

lim_(x rarr-oo)(3x^(3)+2x^(2)-7x+9)/(4x^(3)+9x-2)

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
