expand sqrt((-1+t)^2+(-4-2t)^2+(5+2t)^2)

expand

(- 1 + t)^{2} + (- 4 - 2 t)^{2} + (5 + 2 t)^{2}

9 t^{2} + 34 t + 42

Solution steps

(- 1 + t)^{2} + (- 4 - 2 t)^{2} + (5 + 2 t)^{2}

Expand

(- 1 + t)^{2} + (- 4 - 2 t)^{2} + (5 + 2 t)^{2} : 9 t^{2} + 34 t + 42

= 9 t^{2} + 34 t + 42

\frac{5 ( 1 + 7 )}{3}

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