Question

(a+b+c+d+e)²=?

please solve this guy's it's urgent....​

Answer 1

Answer:

(a+b+c+d+e)²= = a² + b² + c² + d² + e²

Step-by-step explanation:

(a+b+c+d+e)²

(a+b+c+d+e)²= = a² + b² + c² + d² + e²

Answer 2

(a+b+c+d+e)²

= [ (a+b+c)+(d+e)]²

= (a+b+c)²+(d+e)²+2(a+b+c)(d+e)

= [ ( a+b)+c ]² + d² +e² +2de +2( ad +ae+bd+be+cd+ce )

= (a+b)² +c² +d² +e² +2de +2( ad +ae+bd+be+cd+ce )

= a²+b²+c²+d²+e² +2(ab +de +ad +ae+bd+be+cd+ce )
