Question

What is the simplified form of –3z²(z + 2) – 4(z² + 1)? (1 point) Responses –7x² + 1 –7 x ² + 1 –3z³ – 4z² – 6z – 4 –3 z ³ – 4 z ² – 6 z – 4 –3z³ – 2z² – 4 –3 z ³ – 2 z² – 4 –3z³ – 10z² – 4

Answer 1

there is no answer like that

Answer 2

The simplified form of –3z²(z + 2) – 4(z² + 1) is -3z³ - 6z² - 4.

Answer 3

Apologies for the oversight. Let's simplify it again:

–3z²(z + 2) – 4(z² + 1)
= -3z³ - 6z² - 4z² - 4
= -3z³ - 10z² - 4

Therefore, the simplified form is -3z³ - 10z² - 4. Thank you for pointing out the error.
