Celsius, Fahrenheit, Kelvin? One’d colder than the other. Unless ur looking for a detailed answer lol.
if the question is (x + 5)^2, the product is x^2 + 10x + 25.
To solve divide both sides by 4 to cancel out the 4 on the x side to get x alone. Then just do -10/4. That gives you 2.5 so (X=2.5). Hope I helped and have a great day and night
