expand (y+Δ)^3

Solution

expand

(y + Δ)^{3}

Solution

y^{3} + 3Δ y^{2} + 3 Δ^{2} y + Δ^{3}

Solution steps

(y + Δ)^{3}

Apply Perfect Cube Formula:

(a + b)^{3} = a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3}

a = y, b = Δ

= y^{3} + 3 y^{2} Δ + 3 y Δ^{2} + Δ^{3}

expand (x^4+y^4)/(xy(y^2+x^2))expand

\frac{x ^{4} + y ^{4}}{x y ( y ^{2} + x ^{2} )}

expand (2x+1)/(x^2(x+1)^2)expand

\frac{2 x + 1}{x ^{2} ( x + 1 ) ^{2}}

simplify (e^{(-2+i)t}+e^{(-2-i)t})/2 simplify

\frac{e ^{(- 2 + i) t} + e ^{(- 2 - i) t}}{2}

((2+s^5-s^4+2s^3))/(s^4(s^2-s+2))

\frac{( 2 + s ^{5} - s ^{4} + 2 s ^{3} )}{s ^{4} ( s ^{2} - s + 2 )}
