If one of the zeroes of the quadratic polynomial $x^2+3x+k$ is $2$, then find the value of $k$ is

The quadratic polynomial the sum of whose zeros is $-5$ and their product is $6$, is

A quadratic polynomial, the product and sum of whose zeroes are $5$ and $8$, respectively is:

If $\alpha , \beta$ are the zeroes of the quadratic polynomial $p\left(x\right)=x^2-(k+6)x+2(2k-1)$, then the value of $k$, if $\alpha +\beta =\frac{1}{2}\alpha \beta$, is:

If $n$ is a natural number, then $2\left(5^n+6^n\right)$ always ends with:

If $\alpha$ and $\beta$ are roots of quadratic equation $x^2-7x+10=0$, find the quadratic equation whose roots are ${\alpha }^2$ and ${\beta }^2$

Of one zero of the polynomial $x^2+3x+k$ is $2$, then the value of $k$ is 

The zeroes of the polynomial $3x^2+11x-4$ are
