\left(x^{2}+6x\right)\left(14-2x\right)
Use the distributive property to multiply x by x+6.
14x^{2}-2x^{3}+84x-12x^{2}
Apply the distributive property by multiplying each term of x^{2}+6x by each term of 14-2x.
2x^{2}-2x^{3}+84x
Combine 14x^{2} and -12x^{2} to get 2x^{2}.
\left(x^{2}+6x\right)\left(14-2x\right)
