expand (-3e+3z)^2

expand

(- 3 \cdot e + 3 \cdot z)^{2}

9 z^{2} - 18 ez + 9 e^{2}

Solution steps

(- 3 e + 3 z)^{2}

Apply Perfect Square Formula:

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

a = - 3 e, b = 3 z

= (- 3 e)^{2} + 2 (- 3 e) \cdot 3 z + (3 z)^{2}

Simplify

(- 3 e)^{2} + 2 (- 3 e) \cdot 3 z + (3 z)^{2} : 9 e^{2} - 18 ez + 9 z^{2}

= 9 e^{2} - 18 ez + 9 z^{2}

Rewrite in standard form

= 9 z^{2} - 18 ez + 9 e^{2}

r \cdot e^{j (θ + π)}

x^{2} - 2^{2}

e (2 x + 3 y - 2 z + 5)

2 (x + 5 = 16)

(e^{2} x + 1)^{2}
