Answer

false

Work Step by Step

RECALL: For quadratic equations with real number coefficients, if a complex number $a+bi$ is a solution of the equation, then its conjugate $a-bi$ will also be a solution of the equation. Thus, if $2-3i$ is a solution of a quadratic equation with real number coefficients, then its conjugate, which is $2+3i$, will also be a solution of the equation. $-2+3i$ is not the conjugate of $2-3i$. Thus, the given statement is false.
