`15 x^2 + 2x -8`

Find the HCF of 15x^(2) + 8 x - 12, 3x^(2) + x - 2,3x^(2) - 2x , 9x^(2) - 12 x + 4

If y = 2 x^(3)- 15 x^(2) + 36 x + 8 , slove the equation (dy)/(dx)= 12 .

If the equation x ^(2) - 15 - m ( 2x-8) =0 has equal roots, find the value of 'm'.

If the roots of x^4 - 8x^3 + 14 x^2 + 8x - 15=0 are in A.P then the roots are

If the roots of x^4 - 8x^3 + 14 x^2 + 8x - 15=0 are in A.P then the roots are

Using the second derivative , find the out the character of the extrema of the following functions : f(x) = 2x^(3)-15 x^(2) - 84 x +8

Factorise: 15x ^(2)- 26 x + 8

Simplify : 15x-[8x^2 + 3x^2 - {8x^2 - (4-2x-x^3)-5x^3}-2x]
