Olin [163]

Steps:

6 1/4 - 4 3/15 can also be written as 25/4 - 23/5

The LCD of 4 and 5 is 20.

That gives us 125/20 - 92/20.

Now, just subtract the numerators (leave the denominators the same).

That brings us to 33/20, which can be simplified to 1 13/20

Final Answer:

$1\frac{13}{20}$

Find the value of C that completes the square for x^2-2x + C

solniwko [45]

Answer:

C = 1.

Step-by-step explanation:

x^2 - 2x = (x - 1)^2 - 1 so:

x^2 - 2x + C = (x - 1)^2 - 1 + C

So to get a perfect square C must be 1 ( as -1 + 1 = 0):-

(x - 1)^2 - 1 + 1 = (x - 1)^2

Checking this:

x^2 - 2x + 1

= (x - 1)(x - 1) which is a perfect square./
