expand-2(x^2+2Δx^2+Δ^2x^2)+1

expand

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

- 2 x^{2} - 4Δ x^{2} - 2 Δ^{2} x^{2} + 1

Solution steps

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

Expand

- 2 (x^{2} + 2Δ x^{2} + Δ^{2} x^{2}) : - 2 x^{2} - 4Δ x^{2} - 2 Δ^{2} x^{2}

= - 2 x^{2} - 4Δ x^{2} - 2 Δ^{2} x^{2} + 1
