Question

a forma fatorada do polinomio c2 - 2bc - a2 + b2 éa) (b-c+a) (b-c-a)b) (b-c+a) (b+c+a)c) (b-c)a2d) (b+c+a) (b-c-a)

Answer 1

Olá!!

$\\ \mathsf{c^2 - 2bc - a^2 + b^2 =} \\\\ \mathsf{(b^2 - 2bc + c^2) - a^2 =} \\\\ \mathsf{(b - c)^2 - a^2 =} \\\\ \mathsf{((b - c) + a) \cdot ((b - c) - a) =} \\\\ \boxed{\mathsf{(b - c + a)(b - c - a)}}$
