Two people, A and B, are simultaneously calculating a polynomial multiplication problem: $\left(2x+a\right)\cdot \left(3x+b\right)$. A copied the sign of $a$ incorrectly in the first polynomial, writing $+a$ as $-a$, and obtained the result $6x^{2}+11x-10$. B missed the coefficient of $x$ in the second polynomial, writing $3x$ as $x$, and obtained the result $2x^{2}-9x+10$. Calculate the correct result of this polynomial multiplication problem.
