Use the quadratic formula to determine the solutions to the quadratic equation. Write your answers as decimals, and round to the
irina1246 [14]

Answer:

Either   x≈ -1.12    or  x ≈0.45      

Step-by-step explanation:

Using the quadratic formula to solve this, we will follow the steps below;

First, write  down the quadratic formula;

x = -b ±√b² - 4ac /2a

From the question, the equation given is:   6x²+4x−3=0

comparing the equation given withe standard equation  ax² + bx + c=0

a= 6      b= 4    and c = -3

We can now proceed to insert the values into the formula;

x = -4 ±√4² - 4(6)(-3) /2(6)

x = -4 ±√16+72    /12  

x = -4 ±√88    /12

Either x = -4+√88 /12

           x ≈0.45    

OR  

x = -4 -√88   /12

x≈ -1.12

Either   x≈ -1.12    or  x ≈0.45
