#### Multiply using the FOIL method? (x+1)(x+6)

How do you solve this using the FOIL method?:

(x+1)(x+6)

Thank you!

+ more- less
Asked by Courtnee from Mitchell, IN

FOIL stands for First, Outer, Inner, Last...

First:  Multiply the x in the first factor by x in the second factor.  x * x = x^2.

Outer: Multiply the x in the first factor by the 6 in the second factor.  x * 6 = 6x.

Inner:  Multiply the 1 in the first factor by the x in the second factor.  1 * x = x.

Last:  Multiply the 1 in the first factor by the 6 in the second factor.  1 * 6 = 6.

So, our product is x^2 + 6x + x + 6.

After combining like terms, our final answer is x^2 + 7x + 6.

#### Writing a number in scientific notation?

How do you write these two in scientific notation?:

0.000476

...And

3,400,000

Asked by Courtnee from Mitchell, IN

In proper scientific notation, there is only one digit to the left of the decimal point.  So...

0.000476 becomes 4.76 * 10^-4.  The first significant digit is 4, so the decimal point is placed immediately after it.  The decimal point moved four places to the right (smaller numbers) from its original location, so the exponent is -4.

3,400,000 becomes 3.4 * 10^6.  The first significant digit is 3, so the decimal point is placed immediately after it.  The decimal point moved six places to the left (larger numbers) from its original location, so the exponent is 6.

#### How do I come up with a middle term for an equation like x^2+99x-3870=0 in an easy way with out trial and error?

how to simplify an ax^2+bx+c

Asked by Stephanie from Huntington Park, CA

You could try the quadratic formula...

-b +/- SQRT (b^2 - 4ac)

------------------------------

2a

-99 +/- SQRT (99^2 - 4*1*(-3870))

---------------------------------------------

2

-99 +/- SQRT (9801 + 15480)

-------------------------------------

2

-99 +/- SQRT (25281)

----------------------------

2

-99 +/- 159

---------------

So the roots are 30 and -129, and the factors are (x - 30) and (x + 129)

#### The sum of two numbers is 84. The larger exceeds the smaller by 22. What are the numbers?

Word Problems (system of equations)

Asked by Kavon from Young America, MN

Let's say the smaller of the two numbers is x.  The larger of the two must be x + 22.

So, x + x + 22 = 2x + 22 = 84.

Subtract 22 from both sides to get 2x = 62.

Divided by 2 to get x = 31.

So the two numbers are 31 and 31 + 22 = 53.

#### help me please i have a test today

if i have 1/W4-W3

i can factor out W3(W-1)

but would my W3 be under As + B or Asor As3

Asked by Iris from Gilbert, AZ

Is W^3 part of the denominator?  In other words, is the problem (1 / W^4) - W^3 or 1 / (W^4 - W^3)?
