Q. Combine like terms.−y3+5y2+3y2−x−2x−4y2+6y3Answer:
Combine Cubic Terms: Combine the terms that have the same variable raised to the same power. Start with the cubic terms of y, which are −y3 and +6y3.Calculation: −y3+6y3=5y3
Combine Quadratic Terms: Next, combine the quadratic terms of y, which are 5y2, 3y2, and −4y2.Calculation: 5y2+3y2−4y2=4y2
Combine Linear Terms: Now, combine the linear terms of x, which are −x and −2x.Calculation: −x−2x=−3x
Combine Final Expression: Combine the results from the previous steps to get the final expression.Calculation: 5y3+4y2−3x
