What are the solution(s) of the quadratic equation 98 – x2 = 0?

A quadratic equation is of the form of .....[1] where a, b and c are coefficient then, the solution is given by;

Given the quadratic equation:

On comparing the given equation with equation [1] we have;

a = -1 , b = 0 and c =98

then;

Substitute the given values we have;

or

Simplify:

Therefore, the solutions of the given quadratic equation are;

,  

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
