Quizplus · Accepted Answer

To multiply $7z^2$ by each term inside the parentheses, apply the distributive property: $7z^2 \times 5z^2 = 35z^4$, $7z^2 \times 3z = 21z^3$, and $7z^2 \times (-8) = -56z^2$. Combining these gives $35z^4 + 21z^3 - 56z^2$.

Multiply - 7z2(5z2+3z−8)7 z ^ { 2 } \left( 5 z ^ { 2 } + 3 z - 8 \right)7z2(5z2+3z−8)

Multiply
- $7 z ^ { 2 } \left( 5 z ^ { 2 } + 3 z - 8 \right)$
