Which of the following is a equivalent form of the equation

Step-by-step explanation:

-The equation can be simplified by grouping like terms together:

#we then introduce brackets:

we equate to y:

Hence, the equitation's equivalent form is  

The correct option is 2.

Step-by-step explanation:

From the given figure it is clear that the lines DE║RK, in triangle ODE and triangle OKR,

                        (Vertical opposite angles)

                        (Alternate interior angles)

                        (Alternate interior angles)

By using AA property of similarity,

D is correspondence to K, O is correspondence to O, E is correspondence to R.

O ↔ O

Therefore the correct option is 2.
