Im forgetting how to do basic algebra How do you solve some
I\'m forgetting how to do basic algebra :/
How do you solve something like : 4.24= (x)(x)/(.250-x)(.250-x)
I know you can take the sqaure root of both sides and rewrite as: 4.24=x^2/(.250-x)^2
But im not sure where to go from here. Please explain step by step. Thank you!
Solution
4.24 = {x/(.25-x)}2
=> 200x2 = 848x2 + 53 - 424x
(.25 was written as 1/4)
now solve quadratic equation to get 0.16 and 0.49 as answers.
