expand (4+Δx)^2

Solution

expand

(4 + Δ x)^{2}

Solution

16 + 8Δ x + Δ^{2} x^{2}

Solution steps

(4 + Δ x)^{2}

Apply Perfect Square Formula:

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

a = 4, b = Δ x

= 4^{2} + 2 \cdot 4Δ x + (Δ x)^{2}

Simplify

4^{2} + 2 \cdot 4Δ x + (Δ x)^{2} : 16 + 8Δ x + Δ^{2} x^{2}

= 16 + 8Δ x + Δ^{2} x^{2}
