Given the graphic capability of this site, you are going to have to use some imagination!

In the above graphic, P, S and the whole figure are meant to be squares.
The total area is P+Q+R+S = a2
P = (a-b)2
Q = b*(a-b) = (a-b)*b = a*b - b2
R = (a-b)*b = a*b = a*b - b2
and
S = b2
Now, P = {P+Q+R+S} - Q - R - S
= a2 - ab + b2 - ab + b2 - b2
= a2 - 2ab + b2

What is the geometrical proof of a plus b whole square?
In view of the graphic capabilities of this site, you will need to use a fair amount of imagination! Here goes: <------a+b------> <----a----><-b-> +-----------+-----+ |. . . . . . . .|. . . .| |. . . P. . . .|. .Q. | |. . . . . . . .|. . . .| +-----------+-----+ |. . . R. . . .|. .S. | |. . . . . . . .|. . . .| +----------+-----+ Where P = a*a = a2 Q = a*b R = b*a = a*b S = b*b = b2 (a + b)2 = P + Q + R + S = a2 + ab + ab + b2 = a2 + 2ab + b2
What is the square root of ab?
(ab) raised to 1/2 power
The coordinates of a and b are square root of 27 and square root of 15 reapectively find ab?
Find ab
If A(-2-4) and B(-8-4) what is the length of AB?
AB can be found by using the distance formula, which is the square root of (x2-x1)^2 + (y2-y1)^2. In this case, AB= the square root of (-2-(-8))^2 + (-4-(-4))^2 which AB= the square root of 64 + 0 which AB=8.
A minus b plus c whole square?
If you mean (a-b+c)^2, then... a^2 - ab + ac - ab + b^2 - bc + ac - bc + c^2 = a^2 + b^2 + c^2 - 2ab + 2ac - 2bc.
