" (i) "quad 4x^(2)-3x+7

If P = 3x^(3) -5x + 9, Q = 4x^(3) + 5x^(2) -11 and R = 5x^(3) + 4x^(2) -3x +7 , then P -2 Q + R is

If alpha and beta are zeros of p(x) = 4x^(2) + 3x + 7 , "find" (1)/(alpha) + (1)/(beta) .

What must be subtracted from 2x^(4 ) + 4x^(2) - 3x + 7 to get 3x^(3) - x^(2) + 2x + 1 ?

What must be subtracted from 2x^(4) + 4x^(2) -3x+7 to get 3x^(3) -x^(2)+2x +1?
