simplify (x+1)^2+(y-1)^2

Solution

simplify

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

Solution

x^{2} + 2 x + y^{2} - 2 y + 2

Solution steps

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

Expand

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

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

Expand

(y - 1)^{2} : y^{2} - 2 y + 1

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

Group like terms

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