expand (-1+Δx)^2

Solution

expand

(- 1 + Δ x)^{2}

Solution

1 - 2Δ x + Δ^{2} x^{2}

Solution steps

(- 1 + Δ x)^{2}

Apply Perfect Square Formula:

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

a = - 1, b = Δ x

= (- 1)^{2} + 2 (- 1) Δ x + (Δ x)^{2}

Simplify

(- 1)^{2} + 2 (- 1) Δ x + (Δ x)^{2} : 1 - 2Δ x + Δ^{2} x^{2}

= 1 - 2Δ x + Δ^{2} x^{2}
