Answer» Your answer is given-::: a² + b² + c² = (a+b+c)² - 2(ab + bc + ca) The actual formula is (a+b+c)² = a² + b² + c² +2( ab + bc + ca) You can GET this simple formula by multiplying (a+b +c) with (a+b+c). (a+b +c)² = (a+b +c)*(a+b +c) = a*(a+b +c) + b*(a+b +c) + c*(a+b +c) = a² + ab + ac + ab + b² + bc + ca + bc + c² = a² + b² + c² + 2ab + 2bc + 2CA = a² + b² + c² + 2( ab + bc + ca) I HOPE you get the formula and found it simple. If this in not the formula then REPLY |
