**physics**

equal masses m of stone and wood reach thermal equilibrium at T=290. the initial temperature of the wood reach is T=285. find the initial temperature of the stone.(specific heat of wood=1764 and specif heat of stone =882)

**function**

given that f(x)= 3-7x+5x^2-x^3, factorise the polynomial completely, hence state the set of values of x for which the function is equal or less than zero .

**polynomial**

given that the expression ax^3-11x^2+bx+2 is exactly divisible by 2x^2-3x-2, find a and b then factorise completly (do not use long division).

**function ( partial fraction)**

if f(x) ax^2+bx+c , g(x) :1/3x^2+2 and fg(x)= 18x^4+24x^2+11/(3x^2+2)^2. find a ,b and c

**partial fraction**

FIND A, B AND C

**partial fraction**

if f(x) ax^2+bx+c , g(x) :1/3x^2+2 and fg(x)= 18x^4+24x^2+11/(3x^2+2)^"
