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

Answer:

The exact values of roots:

$x_{1}=\frac{-3+\sqrt{33}}{6}$

$x_{2}=\frac{-3-\sqrt{33}}{6}$

Approximation:

$x_{1}\approx0.457$

$x_{2}\approx -1.457$

Step-by-step explanation:

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

Using the quadratic formula:

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

$x=\frac{-3\pm \sqrt{3^2-4\cdot \:3\left(-2\right)}}{2\cdot \:3}$

$x=\frac{-3\pm\sqrt{33}}{2\cdot \:3}$

$x=\frac{-3\pm\sqrt{33}}6}$
