Brian correctly use a method of completing the square to solve the equation X a 2nd plus 7X -11 equals zero Brian‘s first step w

ArbitrLikvidat [17]

Answer:

$(\frac{7}{2})^{2}$

Step-by-step explanation:

Brain correctly use a method of completing the square to solve the equation:

$x^2+7x-11=0$

His First Step is to: Take the Constant Term to the Right Hand Side

$x^2+7x=11$

The Next Step Would be to:

Divide the Coefficient of x by 2
Square It
Add it to both Sides

In this case, the Coefficient of x = 7

Divided by 2 = $\frac{7}{2}$

Squaring It, we have: $(\frac{7}{2})^{2}$

It is this number $(\frac{7}{2})^{2}$ that is added to both sides in the manner below:

$x^2+7x+(\frac{7}{2})^{2}=11+(\frac{7}{2})^{2}$

If I cut 2/3 of a pie and put the big piece on my plate. Then eat 1/4 of the piece. What fraction of the original pie did I eat.

Hunter-Best [27]

If you took $\frac{2}{3}$ of a pie then only ate $\frac{1}{4}$ of that slice, you ate $\frac{1}{4}$ of $\frac{2}{3}$ .

$\frac{2}{3} * \frac{1}{4} = \frac{2}{12}$

Simplify.

$\frac{2}{12} = \frac{1}{6}$

So, you ate 1/6 of the pie.
