expand (2e-9)^2

Solution

expand

(2 e - 9)^{2}

Solution

4 e^{2} - 36 e + 81

+1

Solution steps

(2 e - 9)^{2}

Apply Perfect Square Formula:

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

a = 2 e, b = 9

= (2 e)^{2} - 2 \cdot 2 e 9 + 9^{2}

Simplify

(2 e)^{2} - 2 \cdot 2 e 9 + 9^{2} : 4 e^{2} - 36 e + 81

= 4 e^{2} - 36 e + 81
