Form an equation whose roots are 2, and - 1212.

Solution:

The given roots are 2 and -1212.

Therefore, sum of the roots, S = 2 + (-1212) = 3232

And tghe product of the given roots, P = 2 ∙ -1212 = - 1.

Therefore, the required equation is x22 – Sx + p

i.e., x22 - (sum of the roots)x + product of the roots = 0

i.e., x22 - 3232x – 1 = 0

i.e, 2x22 - 3x - 2 = 0
