int(6x^(3)+15x^(2)-7x-2)/(sqrt(2x^(2)-2x+1))dx

15x^(2)+2x-8

Solve each of the following quadratic equations: 15x^(2)-28=x

Using factor theorem, show that (x-5) is a factor of the polynomial 2x^(3) - 5x^(2) - 28x + 15

Find the values of x such that f(x)=2x^(3)-15x^(2)-84x-7 is a decreasing function.

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

15x^(2)-7x-36=0:

Using the Factor theorem, show that (i) (x-2) is a factor of x^(3)-2x^(2)-9x+18 . Hence factorise the expression x^2-2x^2-9x+18 completely. (ii) (x+5) is a factor of 2x^3+5x^2-28x-15 . Hence factorise the expression 2x^3+5x^2-28x-15 completely. (iii) (3x+2) is a factor of 3x^(3)+2x^(2)-3x-2 . Hence factorise the expression 3x^3+2x^2-3x-2 completely.

If 3x^(2)-7x+2=0 and 15x^(2)-11x+a=0 have a common root and a is a positive real number then the sum of the roots of the equation 15x^(2) -ax +7=0 is
