" 9."x^(2)-4x-5

int((9x^(2)-4x+5))/((3x^(3)-2x^(2)+5x+1))dx

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

Divide 2x^(2) + 9x^(2) + 4x - 15 " by " 2x + 5

Simplify: 9x^4(2x^3-5x^4)xx5x^6(x^4-3x^2)

The sum of 7x^(2) -4x +5 and 9x-10 is ……………..

Solve x ^(5) - 5x ^(4) + 9x ^(3) - 9x ^(2) + 5x -1 =0.

In each of the following find the value of 'a' : (i) 4x^(2)+ax+9=(2x+3)^(2) (ii) 9x^(2)+(7a-5)x+25=(3x+5)^(2)

From the sum of 5x^(2)-3x+7 and 2x-8x^(2)+5 subtract the sum of 13x+9x^(2)+6 and x^(2)-4x+1

If alpha,beta are the roots of x^(2)+2x+5= (then the equation whose roots are (alpha+1)/(alpha),(beta+1)/(beta) is (A) 5x^(2)-9x+4=0 (B) 5x^(2)-8x+4=0 (C) 5x^(2)-10x+4=0 (D) 5x^(2)+9x+4=0
