(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z.
So the factorisation is [(x - y) + z]*[(x - y) - z]
= (x - y + z)*(x - y - z)
Squared stands for 4.
E stands for energy, M for mass, and C squared for the speed of light squared.
The raduis.It's pi, r squared. the r stands for radius!
S squared. You have to find the sides first. S stands for Side.
E stands for Energy, M stands for Mass, C stands for the speed of light.. So Energy = Mass times the Speed of Light squared.
Squared stands for 4.
not sure 100% but my dad told me: e.g. 2(3x + 4) 2 x 3x = 6x 2 x 4 = 8 so its 6x + 8 another one is x(7x + x^2) x times 7x = 7x^2 x times x^2 = x^3 so its 7x^2 + x^3 PS. the ^2 and ^3 stands for sqaured and cubed (:
millimeters squared or mm^2
E stands for energy, M for mass, and C squared for the speed of light squared.
For energy. e stands for energy, m stands for mass, c stands for the speed of light. Plus, the proper form is E=MC squared
I am going to assume that you are referring to the formula "e = mc^2" in this case e is not a distance, but stands for energy. In the formula m stands for mass and c stands for the speed of light squared. This means that the total energy in anything is the mass of the object times the speed of light squared.
The raduis.It's pi, r squared. the r stands for radius!
BB usually stands for Bottom Bracket, the part which holds the cranks/pedals to the bike
S squared. You have to find the sides first. S stands for Side.
E=mc^2 stands for the equation proposed by Albert Einstein in his theory of general relativity. It states that energy (E) is equal to mass (m) times the speed of light (c) squared. This equation shows the relationship between energy and mass, stating that they are interchangeable.
yes the "2" in pi(r2) stands for squared. hopefully you have already asked someone sensible though. this is the formula for the area of a circle(:
E stands for Energy, M stands for Mass, C stands for the speed of light.. So Energy = Mass times the Speed of Light squared.
