You asked:

Evaluate the expression: \(-\left( 2 \cdot \sqrt{98} \right) + 3 \cdot \sqrt{2}\)

MathBot Answer:

\[-\left( 2 \cdot \sqrt{98} \right) + 3 \cdot \sqrt{2} = - 11 \sqrt{2} \approx -15.55634918610404553681857596630668\]

\[\begin{aligned}-\left( 2 \cdot \sqrt{98} \right) + 3 \cdot \sqrt{2}& = - 2 \cdot \sqrt{98} + 3 \cdot \sqrt{2}\\& = - 2 \cdot 7 \cdot \sqrt{2} + 3 \cdot \sqrt{2}\\& = - 14 \cdot \sqrt{2} + 3 \cdot \sqrt{2}\\& = -14 \cdot \sqrt{2} + 3 \cdot \sqrt{2}\\& = -11 \cdot \sqrt{2}\end{aligned}\]
