Identify the zeros of the function f(x) =2x^2 − 2x + 13 using the Quadratic Formula. SHOW WORK PLEASE!! I NEED HELP!!

babunello [35]

Answer:

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

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

in this problem we have

$f(x)=2x^{2} -2x+13$

Equate the function to zero

$2x^{2} -2x+13=0$

$a=2\\b=-2\\c=13$

substitute in the formula

$x=\frac{-(-2)\pm\sqrt{-2^{2}-4(2)(13)}} {2(2)}$

$x=\frac{2\pm\sqrt{-100}} {4}$

Remember that

$i=\sqrt{-1}$

$x=\frac{2\pm10i} {4}$

Simplify

$x=\frac{1\pm5i} {2}$

therefore

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$

A company’s stock was selling at $25 a share a month later it was selling at $30 a share what is the percent increase

rjkz [21]

Answer:

20% increase

Step-by-step explanation:

To find the percent increase, you can divide the increase value by the original: 30/25 = 1.2 --> 120%. Next, since they ask for the percent of increase, you can subtract 1 or 100% from your answer which would give you a final answer of 20% increase.
