Rewrite the equation by completing the square.
4x² + 20r + 25 = 0
(x+...)^2=...

The equation is equal to .

Step-by-step explanation:

Let be the equation , we proceed to rewrite the equation solely by algebraic means:

1) Given

2) Definition of power/Associative property

3)   Perfect square trinomial

4) Distributive property/

5) Definition of power

6) Compatibility with multiplication/Commutative and modulative properties/

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
