Simplify:

(p² + q²) - (q² - r²) - (r² + p²)

(p^{2} - q^{2}) x^{2} + (q^{2} - r^{2}) x + r^{2} - p^{2} = 0

(p^{2} - q^{2}) y^{2} + (r^{2} - p^{2}) y + q^{2} - r^{2} = 0

(p^{2} - 2 p q + q^{2}) - r^{2}

- r^{2} + p^{2} + q^{2} - 2 p q

a (p + q)^{2} + 2 b p q + c = 0

a (p + r)^{2} + 2 p b r + c = 0 (a \neq 0)
