expand (e-2f)^2

expand

(e - 2 f)^{2}

4 f^{2} - 4 e f + e^{2}

Solution steps

(e - 2 f)^{2}

Apply Perfect Square Formula:

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

a = e, b = 2 f

= e^{2} - 2 e 2 f + (2 f)^{2}

Simplify

e^{2} - 2 e 2 f + (2 f)^{2} : e^{2} - 4 e f + 4 f^{2}

= e^{2} - 4 e f + 4 f^{2}

Rewrite in standard form

= 4 f^{2} - 4 e f + e^{2}

0.00024375 \cdot \frac{( 1 + 2.9 s )}{( 1 + 0.85 s )}

t \cdot (H (t - 1) - H (t - 5)) + H (t - 5)

(\frac{1}{y}) ((e^{x} + y^{2}) d x + (x y - \frac{e ^{x}}{y} - 2 y^{2}) d y = 0)

127 \cdot (1 - \frac{1}{( 1 + 0.16 ) ^{10.5}})

- \frac{4}{( x ^{2} - 1 ) ^{2}}
