Question

If the sum of the number and its square is 132, then what is the number

Answer 1

Step-by-step explanation:

let us assume that

x+y=132------->eq1

xy=132--------->eq2

a * (a+1) = 132.

a2 + a = 132

a2 + a - 132= 0

Factor

(a+12)(a-11) = 0

a=-12, a=11

Answer 2

Answer:

11  

Step-by-step explanation:

Let the no. be x.

So, x²+x=132 (Given)

Now,  x²+x-132 = 0

=> x²+12x -11x -132 = 0

=> x(x+12) -11(x+12) = 0

=> (x-11)(x+12) = 0

=> x = 11 , -12
