expand (x+Δx)^2

Solution

expand

(x + Δ x)^{2}

Solution

x^{2} + 2Δ x^{2} + Δ^{2} x^{2}

Solution steps

(x + Δ x)^{2}

Apply Perfect Square Formula:

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

a = x, b = Δ x

= x^{2} + 2 x Δ x + (Δ x)^{2}

Simplify

x^{2} + 2 x Δ x + (Δ x)^{2} : x^{2} + 2Δ x^{2} + Δ^{2} x^{2}

= x^{2} + 2Δ x^{2} + Δ^{2} x^{2}
