Combine x2 terms: Combine the like terms with x2. We have three terms with x2: 5x2, 5x2, and −6x2. Add these terms together.5x2+5x2−6x2=(5+5−6)x2=4x2
Combine constant terms: Combine the constant terms. We have three constant terms: 3, 5, and −7. Add these terms together.3+5−7=(3+5)−7=8−7=1
Combine y term: Combine the like terms with y. In this case, there is only one term with y, which is −7y, so it remains unchanged.
Write final expression: Write the final expression by combining the results from the previous steps. We have 4x2 for the x2 terms, −7y for the y term, and 1 for the constant term.The final expression is 4x2−7y+1.
