expand (x+Δx-1)^2

Solution

expand

(x + Δ x - 1)^{2}

Solution

2Δ x^{2} + Δ^{2} x^{2} - 2Δ x + x^{2} - 2 x + 1

Solution steps

(x + Δ x - 1)^{2}

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

= (x + Δ x - 1) (x + Δ x - 1)

Expand

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

= 2Δ x^{2} + Δ^{2} x^{2} - 2Δ x + x^{2} - 2 x + 1
