In the image below, I showed my work. What you basically do is find the greatest perfect square in each variable and you pull it out of the radical.

Write a personal narrative about what you did and how hard you worked to see success

Life's many roads, lead us in many different directions on different paths,
On these roads of travel we see new people, new things,
Everything appears to be perfect.

But, there shall come times when the road is long,
The journey seems rough and the new people,
Places and things you once saw, are no longer around
You stand alone.

Even though the road may then seem lonely, you keep pushing on -
Praying -
Believing that "Yes I can, Yes I will."
And when no one else believes in you, you believe in yourself.

I know the road was hard, it was long -
Because I traveled the same path.
So don't look back, just continue to push forward -
All that are in the way, move them out - shun the negativity.

Stay head strong, thank God for everything -
Especially for this long harsh road.
Because it was simply
A long journey to success :)

6. Minimum value determined by the formula function f (x) = 2x ²-8x + p was 20. Value f (2) is.

Sergeeva-Olga [200]

$6)\ \ \ f(x)=2x^2-8x+p\\the\ minimum\ value =20\ \ \ \Leftrightarrow\ \ \ y_{\ of\ vertex}=20\ \ \ \Leftrightarrow\ \ \ - \frac{\Delta}{2a} =20\\\\\Delta=(-8)^2-4\cdot2\cdot p=64-8p\ \ \Leftrightarrow\ \ - \frac{64-8p}{2\cdot2} =20\ \ \Leftrightarrow\ \ -16+2p=20\\\\2p=36\ \ \ \Leftrightarrow\ \ \ p=18\ \ \ \Rightarrow\ \ \ \ f(x)=2x^2-8x+18\\\\f(2)=2\cdot2^2-8\cdot2+18=2\cdot4-16+18=8+2=10$

$7)\ the\ shape\ factor\ of\ the\ quadratic\ equation\ 4x^2-13x = -3\\ is\ a=4\ \ \ (\ a>0\ \ \ \rightarrow\ \ \ the\ shape\ is\ \cup\ )\\\\8)\ \ \ the\ turning\ point=(-15;3)\ \ \ \Rightarrow\ \ \ f(x)=a(x+15)^2+3\\\\ the\ graph\ passes\ through\ the\ point\ (-12.0) \ \Rightarrow\ \ 0=a(-12+15)^2+3\\\\\Rightarrow\ \ \ a\cdot3^2=-3\ \ \ \Rightarrow\ \ \ a=- \frac{3}{9} =- \frac{1}{3} \ \ \ \Rightarrow\ \ \ f(x)=- \frac{1}{3}(x+15)^2+3$

$\Rightarrow\ \ \ f(x)=- \frac{1}{3}(x^2+30x+225)+3=- \frac{1}{3}x^2-10x-72\\\\9)\ \ \ 4x^2+px+25=0\\\\\Delta=p^2-4\cdot4\cdot25=p^2-400\\\\two\ solutions\ \ \Leftrightarrow\ \ \Delta>0\ \ \Leftrightarrow\ \ p^2-40>0\ \ \Leftrightarrow\ \ (p-20)(p+20)>0\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \Leftrightarrow\ \ \ p\in(-\infty;\ -20)\ \cap\ (20;\ +\infty)\\-------------------------------$

$the\ Vieta's\ formulas\ to\ the\ quadratic\ equation\ ax^2+bx+c=0\\\\x_1+x_2=- \frac{b}{a} \ \ \ and\ \ \ x_1\cdot x_2= \frac{c}{a} \\------------------------------\\\\x_1+x_2=- \frac{p}{4} \ \ \ and\ \ \ x_1\cdot x_2= \frac{25}{4} \\\\x_1^2+x_2^2=x_1^2+2\cdot x_1\cdot x_2 +x_2^2-2\cdot x_1\cdot x_2 =(x_1+x_2)^2-2\cdot x_1\cdot x_2 \\\\x_1^2+x_2^2=(x_1+x_2)^2-2\cdot x_1\cdot x_2 \ \ \ \Leftrightarrow\ \ \ 12.5=(- \frac{p}{4} )^2-2\cdot \frac{25}{4} \\\\$

Which is a equivalent to 80 1/4x

elena55 [62]

Since you did not provide options for what 80 $\frac{1}{4}$ x could be equivalent to,, it is near to impossible to answer this question fully. I will simplify 80 $\frac{1}{4}$ x for you and then when you can provide the options for me,, I could help you find the answer if you need it.
To simplify this you must reduce the numbers with 4 in order to find your final answer.
20x.
This means that the correct answer to your question is 20x.
Let me know if you have any further questions.
