rld613 Group Title Is there a shortcut when foiling this equation: (6t^2-18t+12)^2 2 years ago 2 years ago

1. rld613 Group Title

I know that there is a shortcut when there are two terms within the bracket but I wonder if there is one for one with 3 terms

2. LoveYou*69 Group Title

Im honestly not sure... Sorry

3. rld613 Group Title

That was a profound answer so u deserve a medal

4. LoveYou*69 Group Title

Thanks

5. rld613 Group Title

Strobe u shld know the answer

Other than noting each time you multiply unlike terms you do this twice, so can just multiply by 2 the first time, I wouldn't say there's many optimisations you can make. These can be done so quickly in your head there's no point grinding over finding the quickest way, though.

Factor out the six, and realize you're really factoring out a six SQUARED. That makes the inside three terms a bit easier to square. $(6t^2-18t+12)^2 = \left(6(t^2-3t+2)\right)^2= 6^2 (t^2-3t+2)^2 = 6^2\left((t-1)(t-2)\right)^2$ And if you wanna go nuts, that last step equals... $6^2(t-1)^2\cdot(t-2)^2$ So yeah. Not exactly a walk through a daisy field, but slightly more manageable. :)

29. Hero Group Title

Math Science courses right now, but each course is 3 and 1/2 weeks long and too dense.

30. rld613 Group Title

31. Hero Group Title

Whatever courses are available. If you want, we can take the same courses.
