Q. Find the product. Simplify your answer.−4(z2−7)
Identify and Distribute: Identify the expression and use the distributive property.We need to distribute −4 to both z2 and −7.−4(z2−7)=−4×z2−4×(−7)
Simplify z2: Simplify −4×z2.Multiply −4 and z2.−4×z2=−4z2
Simplify −7: Simplify −4×(−7).Multiply −4 and −7.−4×(−7)=28
Combine Results: Combine the results from Step 2 and Step 3.We found:−4×z2=−4z2−4×(−7)=28Now, combine these to get the simplified form of −4(z2−7).−4(z2−7)=−4z2+28
