solve for x.

1) The option is correct.

2) The option x=-2 or x=-3 is correct.

3)  The option is correct.

4) The option is correct.

5)  The option x=-2 or x=-3 is correct.

Step-by-step explanation:

1) Given equation is

Now to solve the equation for c:

Squaring on both sides we get

Therefore the option is correct.

2) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

which is a quadratic equation in x.

We can solve it by finding factors

x+2=0 or x+3=0

Therefore  x=-2 or x=-3

Therefore the option x=-2 or x=-3 is correct.

3)  Given equation is

Now to solve the equation for c:

Squaring on both sides we get

Therefore the option is correct.

4) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

Therefore the option is correct.

5) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

which is a quadratic equation in x.

We can solve it by finding factors

x+2=0 or x+3=0

Therefore  x=-2 or x=-3

Therefore the option x=-2 or x=-3 is correct.
