Distribute Negative Sign: Distribute the negative sign to each term inside the second parentheses.We need to apply the negative sign to each term in the second parentheses to remove the parentheses.(5p3−p)−(7p2+4p−3)=5p3−p−7p2−4p+3
Combine Like Terms: Combine like terms.Now, we combine the terms that have the same variable raised to the same power.There are no like terms to combine with 5p3 and −7p2, so they remain unchanged. The terms −p and −4p are like terms and can be combined, as well as the constant term +3.5p3−7p2−p−4p+3=5p3−7p2−(p+4p)+3=5p3−7p2−5p+3
