Question

6. Use the quadratic formula to solve the equation.-3x -x-3-0- 121.135-1t35B- 4135-It170

Answer 1

we have

-3x^2-x-3=0

Using the quadratic formula

we have

a=-3

b=-1

c=-3

substitute in the formula

`x=\frac{-(-1)\pm\sqrt[]{-1^2-4(-3)(-3)}}{2(-3)}`
`x=\frac{1\pm\sqrt[]{-35}}{-6}`

Remember that

i^2=-1

so

`x=\frac{1\pm i\sqrt[]{35}}{-6}=x=\frac{-1\pm i\sqrt[]{-35}}{6}`

answer is option B
