expand ((t+Δt)-1)^2

Solution

expand

((t + Δ t) - 1)^{2}

Solution

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

Solution steps

((t + Δ t) - 1)^{2}

Remove parentheses:

(a) = a

= (t + Δ t - 1)^{2}

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

= (t + Δ t - 1) (t + Δ t - 1)

Expand

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

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