Jambmaths question:
A polynomial in x whose roots are $\tfrac{4}{3}$ and $-\tfrac{3}{5}$ is
Jamb Maths Solution:
$\begin{align} & (x-\tfrac{4}{3})(x+\tfrac{3}{5})=0 \\ & {{x}^{2}}+\tfrac{3}{5}x-\tfrac{4}{3}x-\tfrac{12}{15}=0 \\ & {{x}^{2}}-\tfrac{11}{15}x-\tfrac{12}{15}=0 \\ & 15{{x}^{2}}-11x-12=0 \\\end{align}$
