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.
Thanks!
How could I not have saw that? Thanks.
Not following you. This area is very new to me, in fact we just started this week.
Nope, you're correcting the questions I didn't get right in an exam :0)
2X x X+1 = 2X+2 right? Or does the constant multiplied with the coefficient of the first term only apply to brackets?
And otherwise I'm lost on what I do next. We're revisiting this area after a year or so.
