(a+b+c)^2

1.	(a+b+c)^2
Answer» Answer: ${a + b + c}^{2} = {a + x}^{2} = {a}^{2} + 2ax + {x}^{2} \\ = {a}^{2} + 2a(b + c) + {b + c}^{2} \\ = {a}^{2} + 2ab + 2ac + ( {b}^{2} + {c}^{2} + 2bc) \\ = {a}^{2} + {b}^{2}+ {c}^{2} + 2ab + 2bc + 2ca \\$ Hope that it's HELPFUL to you PLEASE mark as BRAINLIEST plzz then i will FOLLOW u please

Answer:

${a + b + c}^{2} = {a + x}^{2} = {a}^{2} + 2ax + {x}^{2} \\ = {a}^{2} + 2a(b + c) + {b + c}^{2} \\ = {a}^{2} + 2ab + 2ac + ( {b}^{2} + {c}^{2} + 2bc) \\ = {a}^{2} + {b}^{2}+ {c}^{2} + 2ab + 2bc + 2ca \\$

Hope that it's HELPFUL to you
