(bc)2
4
(a+b)(a+b)Also equal to a2+2ab+b2
Pythagoras.
The Pythagoream Thereom is a^2 + b^2 = c^2. Written out it is a squared plus b squared equals c squared.
b+c^2 There is no way to simplify that.
sqrt(a2 + b2) can't be simplified. Neither can (a2 + b2) .
There is an ambiguity whether you square the sum of a plus b, or only b. In any case, I don't think you can simplify this expression.
(bc)2
It is: 2b squared
4b
(a + 2 - b) (a + 2 + b)
Answer: 12
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
Factor it out: (x+2) squared
b= 10
