I assume the way it's written is like this
4x^2 - 8x + 4 - (2x^2 - 3x + 7)
If that's the case, just combine like terms.
Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)
4x^2 - 2x^2 = 2x^2
Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again
-8x + 3x = -5x
And then 4 and -7
4 - 7 = -3
So the simplified version is finally:
2x^2 - 5x - 3
Hope this helped! If you need me to explain anything, don't be afraid to ask.
$135
First, change the mixed number to an improper fraction.
2 1/4 = 9/4
Next, change $60 to an improper fraction.
$60 = 60/1
Then, multiply straight across on both the top and bottom to get 540/4.
Finally, simplify and get 135.
Hope this helped :)
A Multiply the input number by 6 because 2 times 6= 12, 6 times 6= 36, 8 times 6= 48, 9 times 6= 54, and 12 times 6= 72.
The simplest form can be 13/3: 7 or 4.3:7
Answer:
Step-by-step explanation:
Given
Required
Determine f(-1); f(0) and f(2)
Solving f(-1)
In this case, we simply take x as;
Substitute -1 for x in
Apply law of indices
Solving f(0)
In this case, we simply take x as;
Substitute 0 for x in
Solving f(2)
In this case, we simply take x as;
Substitute 2 for x in
