expand (y-2pi)^2

Solution

expand

(y - 2 π)^{2}

Solution

y^{2} - 4 π y + 4 π^{2}

Solution steps

(y - 2 π)^{2}

Apply Perfect Square Formula:

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

a = y, b = 2 π

= y^{2} - 2 y \cdot 2 π + (2 π)^{2}

Simplify

y^{2} - 2 y \cdot 2 π + (2 π)^{2} : y^{2} - 4 π y + 4 π^{2}

= y^{2} - 4 π y + 4 π^{2}
