Simplify into one fraction. -5x/x+3 - 7/x+3
A. -5x-7/x+3
B. -5x+7/x+3
C. -5x-7/(x+3)^2
D. -5x+7/(x+3)^2
The common denominator is (x+3), so we can combine the fractions:
-5x/(x+3) - 7/(x+3) = (-5x-7)/(x+3)
Answer: A. -5x-7/x+3
Well, let's simplify this expression using a bit of clown magic!
First, we need to combine the two fractions over the common denominator (x+3).
So, the expression -5x/(x+3) - 7/(x+3) simplifies to (-5x-7)/(x+3).
Hence, the correct simplified fraction is A. -5x-7/(x+3).
To simplify the expression -5x/x+3 - 7/x+3 into one fraction, we need to find a common denominator for both terms.
The common denominator for both terms is (x+3). Therefore, we can rewrite the expression as:
(-5x - 7) / (x+3)
So, the correct answer is A. -5x-7/(x+3).
To simplify the expression -5x/(x+3) - 7/(x+3), we need to find the common denominator and then combine the fractions.
The common denominator is (x+3) since both fractions have this denominator.
To combine the fractions, we multiply the numerator and denominator of the first fraction -5x/(x+3) by (x+3) to make the denominators the same.
So, (-5x/(x+3)) * ((x+3)/(x+3)) = -5x(x+3)/(x+3)
Multiplying the denominator (x+3) to both numerators, we have:
-5x(x+3)/(x+3) - 7/(x+3)
Now, we can combine the fractions:
(-5x(x+3) - 7)/(x+3)
Expanding the numerator:
(-5x^2 - 15x - 7)/(x+3)
Therefore, the simplified expression is (-5x^2 - 15x - 7)/(x+3).
This means that the correct option is C. -5x-7/(x+3)^2.
