# How do you simplify 4y^2 + 6y^4?

In order for the equation to be able to be simplified more, each term would have to have the exact same variable. For example, if the equation was $4 {y}^{2} + 6 {y}^{2}$, we could simplify it down to $10 {y}^{2}$. However, this is not the case. We have ${y}^{2}$ as the variable for one term and ${y}^{4}$ as the variable for the other term. Therefore, the two terms in the equation are not like terms and cannot be added, which means that this equation can't be simplified any further.
