Simplify $$2\left(\left(\frac{6}{2}\right)x^2-22x+15\right)-6(x^2+5x-18)$$.

Correct option is D

Given: ​

​$$2\left(\left(\frac{6}{2}\right)x^2-22x+15\right)-6(x^2+5x-18)$$ 

Solution: ​

​$$2\left(\left(\frac{6}{2}\right)x^2-22x+15\right)-6(x^2+5x-18) \\ \ \\ = 6x^2-44x+30-6x^2-30x+108 \\ \ \\ = -74x+138$$​​
