(2z/7 - 3x/5)²
You asked:
Evaluate the expression: \({\left( \frac{2 z}{7} - \frac{3 x}{5} \right)}^{2}\)
MathBot Answer:
Evaluated
\(\displaystyle {\left( \frac{2 z}{7} - \frac{3 x}{5} \right)}^{2} = \left(- \frac{3 x}{5} + \frac{2 z}{7}\right)^{2} \)
Expanded
\[{\left( \frac{2 z}{7} - \frac{3 x}{5} \right)}^{2} = \frac{9 x^{2}}{25} - \frac{12 x z}{35} + \frac{4 z^{2}}{49}\]
Factored
\[{\left( \frac{2 z}{7} - \frac{3 x}{5} \right)}^{2} = \frac{\left(21 x - 10 z\right)^{2}}{1225}\]
