If $$\alpha $$ and $$\beta$$ are the zeros of the polynomial $$2x^2+3x^2+5$$, then find value of $$\dfrac{{\alpha + \beta }}{{\alpha \beta }}$$.
Find the zeros of polynomial $$x^2-9x+14$$
If $$\alpha $$ and $$\beta $$ are the zeros of the quadratic polynomial $$25\;{x^2} + 25x + 5$$, then find the value of $$\dfrac{1}{{{\alpha ^2}}} + \dfrac{1}{{{\beta ^2}}}.$$
