There are 4 questions. I will make different questions to sum up the amount of points just please help me lol. Complete the square to re-write the quadratic function in vertex form:

In vertex form the parabola can be expressed as:

y = (x - 2.5)² + 0.75

Step-by-step explanation:

To complete the square, all you need to do is take the term 5x, divide the coefficient in two, and square it.  That is what you need for the third term:

answer: 180

step-by-step explanation:

12-2=10
