For a quadratic of the form

, we can solve by completing the square.
First, we must expand the expression and convert it to the form above.

Completing the square is like forcing a quadratic to be factored like a perfect square trinomial. To do so, we add the square of half of the coefficient b,

, to both sides of the equation.

We then factor like a perfect square trinomial and simplify.

Answer: 4, 2 and 6
Step-by-step explanation:
I just did it
You have that:
1) 7x/4+3 (Name using degree: First degree polynomial),(Name using number of terms:binomial)
2) 5.2x^2-4x+2.5 (Name using degree: Quadratic polynomial),(Name using number of terms:trinomial)
3) 3/5 (Name using degree: zero degree polynomial),(Name using number of terms:monomial)
4) 0.75x^2 (Name using degree: Quadratic degree polynomial),(Name using number of terms:monomial).
C is the answer
x+y<57
50.000x+100.000y>3.000.000
