To determine if the values of 10 and 30 are solutions to a quadratic equation, we first need to know the specific quadratic equation you're referring to. A typical quadratic equation is in the form:
\[ ax^2 + bx + c = 0 \]
We can substitute \( x = 10 \) and \( x = 30 \) into the equation to see if either value satisfies it (i.e., makes the equation true).
Please provide the quadratic equation you would like us to evaluate for these values.
