No 'real' numbers can do that job.
The two numbers are complex.

They are ...

<em>1 + i √3</em>
and
<em>1 - i √3</em> .

Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x2 – 4 into the quadratic formula? Qu

sergejj [24]

Answer:

The answer in the procedure

Step-by-step explanation:

we have

$2=-x+x^{2} -4$

$x^{2}-x-4-2=0$

$x^{2}-x-6=0$

we know that

The formula to solve a quadratic equation of the form

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

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-x-6=0$

$a=1\\b=-1\\c=-6$

substitute in the formula

$x=\frac{-(-1)(+/-)\sqrt{(-1)^{2}-4(1)(-6)}} {2(1)}$

$x=\frac{1(+/-)\sqrt{25}} {2}$

$x=\frac{1(+/-)5} {2}$

$x=\frac{1(+)5} {2}=3$

$x=\frac{1(-)5} {2}=-2$

What percent of $5x$ is equal to $x/5$?

amm1812

Answer:

Step-by-step explanation:

Let y% of 5x is equal to $\frac{x}{5}.$

$y\% \: of \: 5x = \frac{x}{5} \\ \\ \therefore \: \frac{y}{100} \times 5x = \frac{x}{5} \\ \\ \therefore \: y = \frac{x}{5 \times 5x} \times 100 \\ \\ \therefore \: y = \frac{1}{25} \times 100 \\ \\ \therefore \: y = 4 \\ \\ \therefore \: 4\% \: of \: 5x \: is \: equal \: to \: \frac{x}{5}$
