`x^(2)+81+18x`

Find the square root of x^(2) - 18x + 81

Solve the equation 8x ^(3) - 36 x ^(2) - 18 x + 81 = 0 the roots being in A.P.

Factorize x^(2) - 18x + 81 = (…….) 4 - 36x^(2) = (…….)(…….)(……..) x^(2) - 14x +13 = (……..)(………) 9z^(2) - x^(2) - 4y^(2) + 4xy = (……..)(………) abc - ab - c + 1 = (……..)(………)

Evaluate : -7x^(2) + 18x^(2) + 3x^(2) - 5x^(2)

Factorise the x ^(2) + 18x + 65

Factorise : 5x^(2) - 18x -8

If x=2 - 2^((1)/(3)) + 2^((2)/(3)) find the value of x^(3)-6x^(2) + 18x + 18

If one root of 18x^(3) + 81x^(2) + 121x + 60 = 0 is equal to half of the sum of the other two roots then the roots are
