Tran is solving the quadratic equation 2x2 – 4x – 3 = 0 by completing the square. his first four steps are shown in the table. in which step did tran first make an error? step 1 step 2 step 3 step 4tran is solving the quadratic equation 2x2 – 4x – 3 = 0 by completing the square. his first four steps are shown in the table. in which step did tran first make an error? step 1 step 2 step 3 step 4

we have

Step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Step 2

Factor the leading coefficient

Step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

------> Tran made his first mistake in this Step 3

Because Tran did not multiply the term 1 by the leading coefficient in the right side

Step 4

Rewrite as perfect squares

therefore

the answer is

Step 3

c
