Use the quadratic formula to determine the exact solutions to the equation 6x^2 + 4x - 3 = 0

mezya [45]

To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:

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

Plugging it in, we get:

 $\frac{-4\pm \sqrt{16+72} }{12} = \frac{-4\pm 2\sqrt{22}}{12} = \frac{-2\pm \sqrt{22} }{6}$

So the final answer is:

$\frac{ \sqrt{22}-2 }{6}$ and $\frac{-2- \sqrt{22} }{6}$

Answer:

A) 2C

Step-by-step explanation:

The relevant rule of logarithms is ...

log(x²) = 2·log(x)

We know that 64 = 8². So, ...

log(64) = log(8²) = 2·log(8)

We are given that log(8) = C, so 2·log(8) = 2C

Here, all logarithms are to the base 9. That does not change the relations shown.
