Answer 2

$\mathbf{(a-b+c)^{2}=a^{2}+b^{2}+c^{2}-2ab-2bc+2ac}$

Step-by-step explanation:

• Given data

        $\mathbf{(a-b+c)^{2}}$    Taking first two as one

        $\mathbf{\left [ (a-b)+c \right ]^{2}}$

• On opening the bracket of above equation

        $\mathbf{(a-b)^{2}+c^{2}+2(a-b)c}$

        $\mathbf{a^{2}+b^{2}-2ab+c^{2}+2ac-2bc}$

        $\mathbf{a^{2}+b^{2}+c^{2}-2ab-2bc+2ac}$

• Means

        $\mathbf{(a-b+c)^{2}=a^{2}+b^{2}+c^{2}-2ab-2bc+2ac}$
