Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
lawyer [7]

Given:

The quadratic equation is:

12a^2+9a+7=0

To find:

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

Solution:

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

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

We have,

12a^2+9a+7=0

Here, 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}.

Therefore, the correct option is B.

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x)=x^2 to the number of x-intercepts in
Aneli [31]
G was reflected over the x-axis and shifted down by 5. f rests at (0,0) as its only x-intercept and g doesn't have any intercept, because it starts at y=-5 and only goes further down in both x directions.
