Full solution

Q. Find the product. Simplify your answer.\newline4(z27)-4(z^2 - 7)
  1. Identify and Distribute: Identify the expression and use the distributive property.\newlineWe need to distribute 4-4 to both z2z^2 and 7-7.\newline4(z27)=4×z24×(7)-4(z^2 - 7) = -4 \times z^2 - 4 \times (-7)
  2. Simplify z2z^2: Simplify 4×z2-4 \times z^2.\newlineMultiply 4-4 and z2z^2.\newline4×z2=4z2-4 \times z^2 = -4z^2
  3. Simplify 7-7: Simplify 4×(7)-4 \times (-7).\newlineMultiply 4-4 and 7-7.\newline4×(7)=28-4 \times (-7) = 28
  4. Combine Results: Combine the results from Step 22 and Step 33.\newlineWe found:\newline4×z2=4z2-4 \times z^2 = -4z^2\newline4×(7)=28-4 \times (-7) = 28\newlineNow, combine these to get the simplified form of 4(z27)-4(z^2 - 7).\newline4(z27)=4z2+28-4(z^2 - 7) = -4z^2 + 28
