2x^(2)+3x-90

If x in R then range of f(x)=(x^(2)+2x-3)/(2x^(2)+3x-9) is

" If " |{:(x^(2)+x,,x+1,,x-2),(2x^(2)+3x-1,,3x,,3x-3),(x^(2)+2x+3,,2x-1,,2x-1):}|=xA +B then

" If " |{:(x^(2)+x,,x+1,,x-2),(2x^(2)+3x-1,,3x,,3x-3),(x^(2)+2x+3,,2x-1,,2x-1):}|=xA +B then find A and B

" If " |{:(x^(2)+x,,x+1,,x-2),(2x^(2)+3x-1,,3x,,3x-3),(x^(2)+2x+3,,2x-1,,2x-1):}|=xA +B then

f(x) = 3x^(5) +11 x^(4) +90x^(2) - 19x +53 is divided by x +5 then the remainder is______.

f(x) = 3x^(5) +11 x^(4) +90x^(2) - 19x +53 is divided by x +5 then the remainder is______.
