Use the quadratic formula to solve. SHOW ALL STEPS FOR FULL CREDIT. Make sure that the final answer has a simplified radical. 2x² -10x +3

Step-by-step explanation:

If we have the standard form , then we can use the quadratic formula:

First, let's identify our coefficients. We have .

This can be rewritten as .

Therefore, a=2, b=-10, and c=3.

Substitute these values into the quadratic formula. This yields:

From here, simplify. Evaluate the expression under the square root:

Evaluate:

Note that:

Therefore:

We can factor out a 2 from both the numerator and the denominator:

Simplify:

Therefore, our roots are:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
