You know how to solve quadratic equations using algebra, graphs and the quadratic formula. Sometimes one method of solving is more convenient than another method. Describe how you would solve each equation. Give reasons for you answers.

A) 16x^2 = 1600

B) x^2 - 350 = 0

C) x^2 + 10x = 0

I just want to know what you guys think so I have an idea of maybe how to explain my answer.

    How I would solve each?
    first: take sqrt of each side
    second: factor as difference of two squares
    third: factor (x(x+10))=0

    Yeah, kinda.
    I am asking what is the best way to solve each one by either: algebraically, graphing and using the quadratic formula and why you chose that method.
