Simplify the following.
$$3\left(\left(\frac{7}{3}\right)x^{2} - 25x + 12\right) - 7\left(x^{2} + 8x - 16\right)$$​

Correct option is A

​$$\textbf{Given:} \\3\left(\left(\frac{7}{3}\right)x^{2} - 25x + 12\right) - 7\left(x^{2} + 8x - 16\right) \\\\\textbf{Formula Used:} \\a(b + c + d) = ab + ac + ad \\\\\textbf{Solution:} \\3\left(\frac{7}{3}x^{2} - 25x + 12\right) - 7\left(x^{2} + 8x - 16\right) \\= \left(3 \times \frac{7}{3}x^{2}\right) - (3 \times 25x) + (3 \times 12) \quad - \left(7x^{2} + 56x - 112\right) \\= 7x^{2} - 75x + 36 - 7x^{2} - 56x + 112 \\= (7x^{2} - 7x^{2}) + (-75x - 56x) + (36 + 112) \\= -131x + 148 \\$$​​
