Solve the following equation. X cubed minus 6X squared plus 6X equals zero
anyanavicka [17]

We have to solve this equation:

x^3-6x^2+6x=0

Third degree polynomials like this one are not easily solved, but this one has a root at x = 0. The let us factorize this polynomial as x times a second degree polynomial:

\begin{gathered} x^3-6x^2+6x=0 \\ x(x^2-6x+6)=0 \end{gathered}

Now we can find the roots of the quadratic polynomial as:

\begin{gathered} x=\frac{-(-6)\pm\sqrt[]{(-6)^2-4\cdot1\cdot6}}{2\cdot1} \\ x=\frac{6\pm\sqrt[]{36-24}}{2} \\ x=\frac{6\pm\sqrt[]{12}}{2} \\ x=\frac{6\pm\sqrt[]{4\cdot3}}{2} \\ x=\frac{6\pm2\sqrt[]{3}}{2} \\ x=3\pm\sqrt[]{3} \\ x_1=3-\sqrt[]{3} \\ x_2=3+\sqrt[]{3} \end{gathered}

Then, the solutions to the equation are:

x = 0

x = 3 - √3

x = 3 + √3

Charissa is eating out with friends, and it is her turn to pay the gratuity. The bill for the food is $26.50. If she plans to ti
Alex73 [517]
26.50 × 20%
= 26.50 × 0.2
= 5.30
26.50 + 5.30
= 31.80
since charissa doesnt want to leave coins/pennies on the table, you would round it up.
31.80 would then epual 32.00 due to the tenths being above 5 (an 8)

If f(x) = 4х2 +1 and g(x) = х2 – 5, find (f-g)(x).
liq [111]

Answer:

The answer is B

Step-by-step explanation:

f(x) = 4x² + 1

g(x) = x² - 5

(f-g)(x) = 4x² + 1 - (x²-5)

= 4x² + 1 - x² + 5

= 3x² + 6

A = m - n solve for n <br><br> a) n= a plus m<br> b) n= m-a<br> c) n=a-m<br> d) n= -m - a
mariarad [96]
B) n=m-a
Add n to both sides, leaving a+n on the left=m on the right
Subtract a from both sides to get n=m-a
