Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
r-ruslan [8.4K]

Given:

The given quadratic equation is:

12a^2+9a+7=0

To find:

The solution for the given quadratic equation in simplest form by using the quadratic formula.

Solution:

Consider a quadratic equation is defined as ax^2+bx+c=0, then the quadratic formula is:

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

The given quadratic equation is:

12a^2+9a+7=0

We have, a=12,b=9,c=7. Using the quadratic formula, we get

x=\dfrac{-(9)\pm \sqrt{(9)^2-4(12)(7)}}{2(12)}

x=\dfrac{-9\pm \sqrt{81-336}}{24}

x=\dfrac{-9\pm \sqrt{-255}}{24}

x=\dfrac{-9\pm i\sqrt{255}}{24}              [\because \sqrt{-a}=i\sqrt{a}]

The solutions of the given equations are x=\dfrac{-9-i\sqrt{255}}{24} and x=\dfrac{-9+i\sqrt{255}}{24}.

Hence, the correct option is B.
