Questions I couldn't answer:
x^2 - 25/25 + 5x
I can factorize the numerator but not the denominator
I'm familiar with factorizing, canceling and expanding but I've never confronted something like 5x + 25 to expand/factorize.
(2.5 x 10^9)/(5 x 10^3)
in standard form. this isn't algebra but I'm hoping anybody has the patience to answer both.
Write as a single fraction in it's simplest form:
2x/x-1 - 7x-3/x^2-1
Please explain how you got these answers too, in the most efficient method.
Nope, you're correcting the questions I didn't get right in an exam :0)
And otherwise I'm lost on what I do next. We're revisiting this area after a year or so.
