Solve r^2 r 1 = 0 \bmod 7

Evaluate

r^{2} \times r \times 1 = 0 mod 7

Evaluate

More Steps

r^{3} = 0 mod 7

Evaluate

r^{3} = 0

Evaluate

r^{2} \times r = 0

Evaluate

(x^{2} + y^{2}) r = 0

Square both sides of the equation

((x^{2} + y^{2}) r)^{2} = 0

Evaluate

(x^{2} + y^{2})^{2} r^{2} = 0

To covert the equation to rectangular coordinates using conversion formulas,substitute x^{2} + y^{2} for r^{2}

(x^{2} + y^{2})^{2} (x^{2} + y^{2}) = 0

Use substitution

(x^{2} + y^{2})^{3} = 0

Solution

x^{6} + 3 x^{4} y^{2} + 3 x^{2} y^{4} + y^{6} = 0
