Q. Click and drag like terms onto each other to simplify fully.−2x2−5y+7y2−5x−2y+y−4y2
Identify Like Terms: Identify like terms in the expression. Like terms are terms that have the same variables raised to the same powers.−2x2 and −5x are not like terms because they have different powers of x.−5y, −2y, and y are like terms because they all have the variable y to the first power.7y2 and −4y2 are like terms because they both have the variable y to the second power.
Combine Like Terms with y: Combine the like terms involving y to the first power: −5y−2y+y.−5y−2y+y=−5−2+1=−6y
Combine Like Terms with y2: Combine the like terms involving y to the second power: 7y2−4y2.7y2−4y2=3y2
Rewrite Expression: Now, rewrite the expression with the combined like terms: −2x2−5x−6y+3y2
Check for Further Simplifications: Check if there are any more like terms to combine or any other simplifications that can be made.There are no more like terms, and the expression cannot be simplified further.
