Question

What is the Formula of (a-b+c)² ?

Answer 1

your answer is given below

$=(a-b+c)*(a-b+c)</p><p> \\ = {a}^{2} - ab + ac - ab + {b}^{2} - bc + ca - bc + {c}^{2} \\ = {a}^{2} + {b}^{2} + {c}^{2} - 2ab - 2bc + 2ac$

please don't forget to mark my answer as the brainliest one.

Answer 2

If you have face a problem ,that's why I will written the same answer with the help of keypad...

We'll, it's more of an expression

First lets put it into a more readable from;

(a-b+c) (a-b+c)

For this, we select a term, and multiply it with each term in the other bracket and then repeat until all terms have been selected

so we will have

aa-ab+ac-ba+bb-bc+ca-cb+cc

which can be rewritten into :

a^+b^+c^-2ab-2bc+2ac [ ^ mean square ]

Or, if you like

a^+b^+c^-2(ab+bc-ac)

The end... thanks
