Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form. his answer is f(x) = ()2 – 5.

Step-by-step explanation:

Given is a quadratic equation as

To complete the square we have to suitably add and subtract a term depending on the coefficient of x.

Here coefficient of x =6 and coefficient of x square =1

Hence we have to add (6/2)^2=9 to make it a perfect square

Now we completed the square and made it in vertex form

Vertex is (-3,-5)

and

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

5 + 8 +7 + 4 + 0 +1 = 25
