`5x^(3)+4x^(2)+7x`

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

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

Evaluate: (i) int(5x^(2) + 2x^(-5) - 7x + 1/(sqrt(x)) +5/x) dx (ii) int(3sinx - 4 cosx + 5 sec^(2) x - 2cosec^(2)x) dx (iii) int(1-x)(2+3x)(5-4x)dx (iv) int((3x^(4) - 5x^(3) + 4x^(2) -x + 2)/(x^(3)))dx , (v) int(x^(2) + 1/(x^(2)))^(3) dx

Subtract: 7x^(4)-5x^(3)+4x^(2)+3x-3 from 6x^(4)-4x^(3)-8x^(2)-2x+7

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

Multiply (2x^(3) - 5x^(2) - x + 7) by (3 - 2x + 4x^(2))

int(x^(6)+7x^(5)+6x^(4)+5x^(3)+4x^(2)+3x+1)e^(x)dx equals
