Find the value of x cubed minus 2x squared minus 7x + 5 of x=1/2-√3

Svetach [21]

9514 1404 393

Answer:

Step-by-step explanation:

For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...

f(x) = ((x -2)x -7)x +5

and ...

x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3

Then ...

f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5

= (3+2√3 -7)(2+√3) +5

= 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5

f(1/(2 -√3)) = 3

_____

If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.

Hi there!

»»————-　★　————-««

I believe your answer is:

Option A; $m \leq\frac{3}{5}$

»»————-　★　————-««

Here’s why:

We can use inverse operations to solve for 'm'.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'm':}}\\\\5m+1\leq4\\--------\\\rightarrow 5m + 1 - 1 \leq 4 - 1\\\\\rightarrow 5m\leq3\\\\\rightarrow \frac{5m\leq3}{5}\\\\\rightarrow \boxed{m\leq\frac{3}{5}}$

⸻⸻⸻⸻

Any number that is less than or equal to the value of three-fifths would work.

The option that is less than or equal to (3/5) is option A.

Assuming that there are more options than the options shown, choose the numbers that are less than or equal to (3/5).

Hope this helps you. I apologize if it’s incorrect.
