If `P = 5x^3 + 3x^2- 4x + 1, Q = 3x^3 + 5x2 + 3x - 8 and R = 6x^3 - 4x^2-7x +3` find (P+Q)-R

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 A = 4x^(3) -8x^(2), B = 7x^(3) -5x + 3 and C = 3x^(3) + x - 11 , then find 2A -3B + 4C

If P = 8x^(4) + 6x^(3) - 15 x^(2) + 27 x - 20 and Q = 2x^(2) + 3x - 4 , then find the remainder when P is divided by Q .

Let P(x) = 4x^(2) - 3x + 2x^(3) + 5 and q(x) = x^(2) + 2x + 4 find p ( x) - q(x) .

Add: 2x^(3) - 9x^(2) + 8, 3x^(2) - 6x - 5, 7x^(3) - 10x + 1 and 3 + 2x - 5x^(2) - 4x^(3)

If (x-3) is the HCF of x^(3) - 2x^(2) +px + 6 and x^(2) - 5x +q, find 6p +5q

If P = {x : 7x - 4 gt 5x + 2, x in R} and Q = {x : x - 19 ge 1 - 3x, x in R} , find the range of set P cap Q and represent it on a number line.
