The problem
Factorize: [itex] a^{2}-\left ( b+c \right )^{2}[/itex]
expanded it to see if I can find any solution:
[itex] \left ( b+c \right )^{2}=b^{2}+2bc+c^{2}[/itex][itex] a^{2}-\left ( b^{2}+2bc+c^{2} \right ) [/itex][itex] a^{2}- b^{2}-2bc-c^{2} \right )[/itex]
But I can’t get any further.
What should I do now to simplify it? Please explain and show me a couple of clues or something?
