When multiplying terms with exponents, you add the exponents of like bases. Thus, $8x^2 \times -2x^7 = -16x^{2+7} = -16x^9$ and $8x^2 \times -4x^6 = -32x^{2+6} = -32x^8$, resulting in $-16x^9 - 32x^8$.

Multiply - 8x2(−2x7−4x6)8 x^{2}\left(-2 x^{7}-4 x^{6}\right)8x2(−2x7−4x6) A) −16x9−32x8-16 x^{9}-32 x^{8}−16x9−32x8 B) −16x9+32x8-16 x^{9}+32 x^{8}−16x9+32x8
