Question

The quadratic formula gives which roots for theequation 3x² + 3x =2?

Answer 1

Answer: the person above is correct

Step-by-step explanation: APEX

Answer 2

The exact values of roots:

`$x_(1)=(-3+√(33))/(6)$`

`$x_(2)=(-3-√(33))/(6)$`

Approximation:

`x_(1)\approx0.457`

`x_(2)\approx -1.457`

Explanation:

`3x^2 + 3x =2\\3x^2 + 3x -2=0`

Using the quadratic formula:

`$x=(-b\pm √(b^2-4ac))/(2a)$`

`$x=(-3\pm √(3^2-4\cdot \:3\left(-2\right)))/(2\cdot \:3)$`

`$x=(-3\pm√(33))/(2\cdot \:3)$`

`$x=\frac{-3\pm√(33)}6}$`
