Which statement describes how to solve 3sqrt(x^2-6)=3sqrt(2x+2)
square both sides and then solves the resulting quadratic equations
square both sides and then solve the resulting cubic equations
cube both sides and then solve the resulting quadratic equations
cube both sides and then solve the resulting cubic equations

Option 1 - Square both sides and then solves the resulting quadratic equations

Step-by-step explanation:

Given : Expression  

To find : Which statement describes how to solve given expression?

Solution :

The best option to solve the given expression is 'Square both sides and then solves the resulting quadratic equations'.

Now, We apply the statement to prove it.

Squaring both side,

(Taking 9 common)

Solving the quadratic equation,

Applying middle term split,

Therefore, The solution of the expression is x=2,-4.

Hence, Option 1 is correct.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
