Math Problem help? stupid babysitting! (6th grade word problem math)?

It's like asking what is (a-b)^2 a^2 -2ab + b^2 so (2x-5)^2 = 4x^2 -20x + 25.

So your problem is what does (2x-5)^2 equal when you multiply it out, so that it's just a string of things being added and subtracted together rather than a thing with parentheses. The underlying concept here is that when you multiply a sum of things, like (2x-5), times anything, call it "a", that's really the same thing as multiplying "a" by each part of the sum, 2x and -5 in this case, and adding them up. So like you can visualize in your head that five threes plus five fours is the same as five three-plus-fours.

Make sense? Visualize a grid of 5 by 7: O O O . O O O O O O O .

O O O O O O O . O O O O O O O . O O O O O O O .

O O O O So now when you're multiplying a sum by not just one thing, by not just a number "a", not just like five in the grid above, but rather by a whole other sum of things, all you have to do is the same thing like you did with the five sevens REPEATEDLY. In this case, TWICE. (2x-5) to the second power, or (2x-5) squared, or (2x-5)^2 = (2x-5)*(2x-5) = 2x*(2x-5) + -5*(2x-5) = (2x*2x) + (2x*-5) + (-5*2x) + (-5*-5) = "First"+"Outer"+"Inner"+"Last" = 4x^2 - 10x -10x + 25 = 4x^2 - 20x + 25 FOIL is an unnecessary acronym that's supposed to help you remember how to do it by rote memory, it stands for "First Outer Inner Last", mainly all it does is impede people from actually learning things and understanding them, understanding why things work the way they do.

Which I hope you now do. Btw "binomial" just means any sum of two terms that is taken as a whole, like (2x-5) or (5b+10c^3), for instance. Just a fancy sounding word for something simple.

H (3) = - 36 + 24 + 12 = 0 Hits ground after 3 sec.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
