Question

Please solve this maths blanks from the identity
(a+b+c)² = a²+b²+c²+2ab+2bc+2ca

On actual measurement, we get
a = …….. , b = …….. , c = …….. ,
So, a² = …….. , b² = …….. , c² = …….. ,
ab = …….. , bc = …….. , ca = …….. ,
2ab = …….. , 2bc = …….. , 2ca = …….. ,
a + b+c = …….. ,
and (a + b+c)² = …….. ,
Hence, (a + b+c)² = a² + b² + c² + 2ab + 2bc +2ca

Answer 1

Answer:

used to make the square PQRS = a² + b² + c² + ab + ab + bc +bc +ca+ca = (a² + b² + c² + 2ab + 2bc + 2ca) …(ii) From Eqs. (i) and (ii), we have (a + b+c)²

Step-by-step explanation:

(a+b+c)² = a²+b²+c²+2ab+2bc+2ca.
