Answer:

(a+b)(a-b)

Step-by-step explanation:

\\ \sf\longmapsto (a+b)(a-b)

\\ \sf\longmapsto a(a-b)+b(a-b)

\\ \sf\longmapsto a^2-ab+ba-b^2

\\ \sf\longmapsto a^2-ab+ab-b^2

\\ \sf\longmapsto a^2-b^2

Hoang has been a nurse for 5 years longer than Bill. Three years ago she had been there twice as long? How long has each been th
ZanzabumX [31]

Answer:

Bill: 8 years

Hoang: 13 years

Step-by-step explanation:

Let's say Hoang has been a nurse for H years and Bill has been a nurse for B years.

Hoang has been a nurse for 5 years longer than Bill. This means that B + 5 = H

Next, 3 years ago, she had been there twice as long.

(B-3) and (H-3) represent Bill and Hoang 3 years ago respectively.

(B-3) * 2 = (H-3)

We thus have two equations

B+5 = H

(B-3) * 2 = H-3

Substitute B+5 for H in the second equation

2*B - 6 = B+5-3

2B-6 = B+2

add 6 to both sides to put all the constants on one side

2B = B + 8

subtract B from both sides to isolate the variable

B = 8

H = B+5 = 13

Which of the following are solutions to the equation below? x2 + 6x + 9 =6
svetoff [14.1K]
The correct answer would be 3 +/- \sqrt{6}

In order to solve for this you must first get the equation equal to 0. 

x^2 + 6x + 9 - 6 ----> simplify like terms
x^2 + 6x + 3

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c. 

a = 1 (because it is the coefficient to x^2)
b = 6 (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation. 

\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}

\frac{-6 +/- \sqrt{6^{2} - 4(1)(3) } }{2(1)}

3 +/- \sqrt{6}

And those would be your two answers.
