1️⃣ -1
2️⃣ 2
3️⃣ 3
4️⃣ -5​

Answer 1

3. 3 I think so sometimes my calculations also wrong ok

Answer 2

Given,

The given mathematical equation is = x(x+3)-6 = 12

To find,

The value of x from the given equation.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Simplification of the given equation :

x(x+3)-6 = 12

x²+3x-6 = 12

x²+3x-18 = 0

x²+6x-3x-18 = 0

x(x+6)-3(x+6) = 0

(x-3) (x+6) = 0

So,

x-3 = 0

x = 3

And,

x+6 = 0

x = -6

Now, 3 is given as a option in the question, so we will consider this as the final value of the x.

Hence, the value of x can be 3 (option 3).
