Distribute x2: Distribute x2 to each term inside the parentheses.We will use the distributive propertya(b+c)=ab+ac to multiply x2 with each term inside the parentheses.x2∗(−3x2)+x2∗(7x)
Multiply terms: Multiply the terms.When multiplying powers with the same base, we add the exponents.x2×(−3x2)=−3x2+2=−3x4x2×(7x)=7x2+1=7x3
Combine results: Combine the results from Step 2.−3x4+7x3This is the simplified form of the expression after distributing and multiplying.
