Answer:
The correct option is 2. 16 is added to both sides of the equation.
Step-by-step explanation:
The given equation is
[tex]x^2-8x=-10[/tex]
If an expression is defined as [tex]x^2+bx[/tex], then we need to add [tex](\frac{b}{2})^2[/tex] in the expression to make it perfect square.
In the given equation b=-8.
[tex](\frac{b}{2})^2=(\frac{-8}{2})^2=(-4)^2=16[/tex]
We need to add 16 on both the sides to solve by completing the square.
Therefore the correct option is 2. 16 is added to both sides of the equation.
