expand (4e-d)^2

expand

(4 e - d)^{2}

d^{2} - 8 e d + 16 e^{2}

Solution steps

(4 e - d)^{2}

Apply Perfect Square Formula:

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

a = 4 e, b = d

= (4 e)^{2} - 2 \cdot 4 e d + d^{2}

Simplify

(4 e)^{2} - 2 \cdot 4 e d + d^{2} : 16 e^{2} - 8 e d + d^{2}

= 16 e^{2} - 8 e d + d^{2}

Rewrite in standard form

= d^{2} - 8 e d + 16 e^{2}

∣ 16 + 4 (3 q + p) ∣

π (60 ln (2) - \frac{27}{4})

(7 d - 9 e + 2 f) \cdot 3 f

(7 x y) (40 x y^{2} z)

- cos (3 (1 + 3 x^{2}))
