Answer» Answer :- <P> [D] 1 + p Explanation :- In option (a) variable has a square it is LIKE quadratic equation also same in option (b) it has also square and it have 2 variable, in that case we see the option (C) is only a numerical it didn't have any variable, because of that it also wrong. Now in the option (d) it have only one variable and no have any square or any thing. ⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛⬛ More to know : ⚫ GENERAL formula of quadratic equation : ax² + bx + c = 0
