Factor ab - 2ac plus b squared - 2bc?
4
Factor ab - 2ac plus b2 - 2bc?
ab-2ac+b^2-2bc
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.
Can you show a b c the whole square?
It's easy to evalute (a + b + c)2..... Let x = (a + b)....then expand (x + c)2 as you would normally in the case of binomial expansion......which is : (x + c)2 = x2 + c2 + 2xc ......(1) Now, replace x with (a + b) in (1).....then it becomes....... (a + b)2 + c2 + 2.(a + b).c .....(2) Just a little more to be done here ( now we expand (2) in the last step)........ a2 + b2 + 2ab + c2 + 2ac + 2bc (rearranging this we get) a2 + b2 + c2 + 2ab + 2bc + 2ac . this happens to be the expansion for (a + b = c)2
What is the surface area of a rectangular prism with 2cm front and back and 10cm top and bottom and 5cm left and right?
2ab+2bc+2ac=Surface area of a rectangular prism C=2 B=10 A=5 2(5)(10)+2(10)(2)+2(5)(2)= 100+40+20=160cm^2
