What is your strategy for graphing a linear equation? Do you think you can use the same strategy to graph a quadratic equation?
Nina [5.8K]
To graph a linear equation, you use y=mx+b. To graph a quadratic equation you use y=ax^2 + bx + c. You cannot use the same strategy to graph a quadratic equation, as in order to graph a quadratic equation, you would execute it differently. The idea is the same however, to plug numbers into the equation to find your coordinates.

Find the value of c such that the expression is a perfect square trinomial
Alika [10]

Answer:

c = 4

Step-by-step explanation:

In a perfect square trinomial, the following relationship is true:

(x+y)^2=x^2+2xy+y^2

In order for the given expression to be a perfect square trinomial:

x^2=x^2\\4x=2xy\\c=y^2

Solving for 'c':

4x=2xy\\y=2\\c=y^2=2^2\\c=4

Therefore, c must be equal to 4.
