Question

a=b=c then find the value of (a+b+c) ^2/a^2+b^2+c^2​

Answer 1

The Answer Is 3a^2 3b^2 3c^2

Since all the variables equal each other, you may pick one variable to copy in the equation.

${a}^{2} + a^{2} + {a}^{2} = 3 {a}^{2}$

And since they're the same numbers, squaring a will have no effect in the equation.
