Q. Multiply. Write your answer in simplest form.q22q+3×(10q2−13q+4)
Identify expressions: Identify the expressions to be multiplied.We have the expression (2q+3)/q2 to be multiplied by (10q2−13q+4).
Multiply expressions: Multiply the expressions.To multiply the expressions, we multiply the numerators together and place the result over the common denominator.The expression becomes: q2(2q+3)⋅(10q2−13q+4).
Distribute terms: Distribute the terms in the numerators.We distribute (2q+3) across (10q2−13q+4) to get:2q×10q2+2q×(−13q)+2q×4+3×10q2+3×(−13q)+3×4.
Perform multiplication: Perform the multiplication.Now we calculate each term:2q×10q2=20q32q×(−13q)=−26q22q×4=8q3×10q2=30q23×(−13q)=−39q3×4=12So the expression becomes: (20q3−26q2+8q+30q2−39q+12)/q2.
Combine like terms: Combine like terms in the numerator.We combine the q2 terms and the q terms:20q3+(−26q2+30q2)+(8q−39q)+12This simplifies to: 20q3+4q2−31q+12.So the expression is now: (20q3+4q2−31q+12)/q2.
Simplify expression: Simplify the expression by canceling out common factors.We notice that each term in the numerator has at least a factor of q2. However, since the highest power of q in the numerator is q3, we cannot cancel out the entire q2 from the denominator across all terms. We can only simplify the terms that have q2 as a factor.The expression becomes: 20q−31+q212.
