Question

# If one zero of the quadratic polynomial $${x^2} + 3x + k$$ is 2, then find the value of k.

Solution

## Given polynomial $$x^2+3x+k=f(x)$$Also, given that $$2$$ is one of the zeros of the polynomial.$$\therefore \ f(2)=0$$$$\Rightarrow 4+6+k=0$$$$\Rightarrow \ k=-10$$Hence, the value of $$k$$ is $$-10$$Mathematics
