Solve the following quadratic equation using the quadratic formula. Which of the following expressions gives the numerators of t
Illusion [34]

I hope the choices for the numerators of the solutions are given.

I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = 10, b = -19 and c = 6.

Next step is to plug in these values in the above formula. Therefore,

x=\frac{(-19)-\pm\sqrt{(-19)^2-4*10*6}}{2*10}

=\frac{19\pm\sqrt{361-240}}{20}

=\frac{19\pm\sqrt{121}}{20}

=\frac{19\pm11}{20}

So, x=\frac{19-11}{20} ,\frac{19+11}{20}

x=\frac{8}{20} , \frac{30}{20}

So, x= \frac{2}{5} ,\frac{3}{2}

Hope this helps you!
