Solve for x.<br><br> (x - 4)(x -4) = 0<br><br> A. -16<br> B. -4<br> C. 4<br> D. 16
hichkok12 [17]

Answer:

C; x = 4

Step-by-step explanation:

In these equations we can FOIL. That is, multiply the first numbers of both groups, the outside numbers, the inside numbers, and whatever is left last.

so x • x + x • -4 + -4 • x + -4 • -4 = 0

= x^2 + -4x + -4x + 16 = 0 (two negatives multiplied together always equal a positive number)

The X's can be added together, but not the X^2, since it has a different base.

So we get x^2 + -8x + 16 = 0 ( -4 + -4 = -8). We call this factored form.

In reality, we have two equations, x-4 and x-4, which are equal to zero. So x-4 =0 and x-4 =0. We can add 4 to both sides for the two equations, so x = 4 and x = 4. Since both solutions of x are the same, we only have one solution, x = 4.

You can honestly ignore the top paragraph if you want, I'm just a huge math nerd.

If 1/a + 1/b =1/c and ab=c,what is the average of a and b?
goblinko [34]
If we solve the left side of the given equation,
                                  1/a + 1/b = 1/c
 we get an answer of,
                                    b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.
