Use the quadratic, x^2+18x=25 to answer the following questions. Part A: find the value of c that will result in a perfect square trinomial.
x2 + 18x + c = 25+ c

Part B: Rewrite the above equation into a perfect square binomial form.
(x+__)^2

Part C: What is the value of x?

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
