expand (2-e)^2

Solution

expand

(2 - e)^{2}

Solution

4 - 4 e + e^{2}

+1

Decimal Notation

0.51592 \dots

Solution steps

(2 - e)^{2}

Apply Perfect Square Formula:

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

a = 2, b = e

= 2^{2} - 2 \cdot 2 e + e^{2}

Simplify

2^{2} - 2 \cdot 2 e + e^{2} : 4 - 4 e + e^{2}

= 4 - 4 e + e^{2}
