expand (2+Δx)^2

Solution

expand

(2 + Δ x)^{2}

Solution

4 + 4Δ x + Δ^{2} x^{2}

Solution steps

(2 + Δ x)^{2}

Apply Perfect Square Formula:

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

a = 2, b = Δ x

= 2^{2} + 2 \cdot 2Δ x + (Δ x)^{2}

Simplify

2^{2} + 2 \cdot 2Δ x + (Δ x)^{2} : 4 + 4Δ x + Δ^{2} x^{2}

= 4 + 4Δ x + Δ^{2} x^{2}
