You asked:
Evaluate the expression: \(\frac{{a}^{2}}{121} + \frac{{b}^{2}}{49} + \frac{2 a b}{77}\)
MathBot Answer:
Evaluated
\(\displaystyle \frac{{a}^{2}}{121} + \frac{{b}^{2}}{49} + \frac{2 a b}{77} = \frac{a^{2}}{121} + \frac{2 a b}{77} + \frac{b^{2}}{49} \)
Factored
\[\frac{{a}^{2}}{121} + \frac{{b}^{2}}{49} + \frac{2 a b}{77} = \frac{\left(7 a + 11 b\right)^{2}}{5929}\]
