​Simplify: $$3 \left( (\frac{7}{3}) x^2 - 27x + 14 \right) - 7 \left( x^2 + 8x - 11 \right)$$​​

Correct option is C

Given:

​$$3\!\left(\frac{7}{3}x^{2}-27x+14\right)-7(x^{2}+8x-11)$$​

Solution:

$$3\!\left(\frac{7}{3}x^{2}-27x+14\right)-7(x^{2}+8x-11) \\ \ \\ = 7x^{2}-81x+42-7x^{2}-56x+77 \\ \ \\=-137x+119$$​
