Solve for `x`
`1!+2!+3!+………….+(x-1)!+x!=k^(2)` and `k epsilonI`

Solve for x: 2(x^(2) -1) = x( 1-x)

Solve (k) 1-1/3 + 3̶2/3

Solve : (x-2)^(2)+1=2x-3

Solve: 2x^2+sqrt 3x+1=0

Solve : 3(2-x)ge 2(1-x)

Solve (tan 3x - tan 2x)/(1+tan 3x tan 2x)=1 .

If x - 1 is a factor of x^(5) - 4x^(3) +2 x^(2) - 3x + k = 0 then k is

Let n and k be positive integers such that n ge K(K + 1)/2 . Find the number of solutions ( x_(1) , x_(2) , x_(3),………., x_(k) ) x_(1) ge 1, x_(2) ge 2, ……….. X_(k) ge k , all integers satisfying the condition x_(1) + x_(2) + x_(3) + ………. X_(k) = n .

If zeros of f(x) = x^(3) - 12 x^(2) + 39 x + k are in AP, find k.

solve |(2)/(x-3)|gt 1,x!=3 .
