Type 1
Equations of the form
Solve for t and then obtain the value of x.
Type 2
Equations of the form


Type 3
Equations of the form

Now these equations can be solved for x.
Type 4
(x + a)(x + b)(x + c)(x + d) = 0In such equations, if the sum of any two constants a, b, c, d is equal to
sum of the other two, then such pairs are multiplied and solve themif a+b = c+d = m then,
Now put x2 + mx = t then, (t + ab)(t + cd) + k = 0.
This can be solved for t and then obtain the value of x.Type 5
