Solve 5x^2 - 7x + 2 = 0 by completing the square.
what is the constant added on to form the perfect square trinomial?
a. 49/4
b. 49/25
c. 49/100

 The correct option is (c)

Step-by-step explanation:  We are given to solve the following quadratic equation by the method of completing the square:

Also, we are to find the constant added on both sides to form the perfect square trinomial.

We have from equation (i) that

So,

Thus, the required solution is and the value of the constant added is

Option (c) is correct.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
