expand (dg-xn)^2

Solution

expand

(d g - x n)^{2}

Solution

d g^{2} - 2 n x d g + n^{2} x^{2}

Solution steps

(d g - x n)^{2}

= (d g - n x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

a = d g, b = x n

= d g^{2} - 2 d gx n + (x n)^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

= d g^{2} - 2 n x d g + n^{2} x^{2}
