Question

What are the solutions of 12 - x2 = 0?
O x=2,5 and x = -2/3
O x=373 and x = -312
O x= 4/5 and x = -4/3
* x= 6 and x = -6

Answer 1

$12 - 2x = 0 \\ - 2x = 0 - 12 \\ -2x = - 12 \\ - x = - 12 \div 2 \\ - x = - 6 ( - can \: be \: cancelled \: if \: its \: in \: both \: side)\\ x = 6$

Answer 2

the solutions for the quadratic equation are 3.46 and -3.46

How to solve the quadratic equation?

Here we have the equation:

12 - x^2 = 0

To solve this, first, we add x^2 on both sides:

12 = x^2

Now we can just apply the square root on both sides, to get:

±√12 = x

±3.46

So the solutions are 3.46 and -3.46
