=(x+1)(x+3)

but theres a couple i don't understand such as
x^2 – 2xy + 3y2

Two particles, of masses x kg and 0.1kg, are moving towards each other in the same straight line collide directly. immediately before the impact, the speeds of the particles are 2ms-1 and 3ms-1 respectively.

a) Given that both particles are brought to rest by the impact, find x?

b) Given instead that the particles move with equal speeds of 1ms-1 after the impact, find the three possible values of x?

first of all im not asking you to do my homework. Im doing IB High Level Math and am struggling so i asked the teacher for some practice work. if you could show your work so i can understand the steps to solve the problems that would be great

1. Find the range of values for p such that 3x^2+3px+p^2=1 has real roots.

2. Find the exact solutions to the equation √(3x-2) - √(x-2)=1

3.solve the inequality (x^2-2x-10)/(x+1) >= 2

We have a chemistry project in which we choose one element from each family and summarize its characteristics. I wouldn't want to go through dozens of websites looking for information. I also would like avoid a page long bibliography. I'm sure there's a site out there where your can find basic information on each element. Does anybody know of such a website? Thanks! Any help would be much appreciated!

I've looked some equations up on google- but they aren't what I'm looking for.
My teacher told me drag is just the velocity squared.... is he right?
