Given : The square of a number added to the number gives 30.
To Find : Which of the following is the number
(a) 6
(b) -5
(c) -6
(d) 7
Solution:
Assume that Number is N
square of a number = N²
The square of a number added to the number gives 30.
=> N² + N = 30
=> N² + N - 30 = 0
Using Middle term split
=> N² + 6N - 5N - 30 = 0
=> N(N + 6) - 5(N + 6) = 0
=> (N - 5)(N + 6) = 0
=> N = 5 or N = - 6
From the given options -6 is the correct answer
