What is the difference <br> A <br> B<br> C<br> D

aksik [14]

Answer:

D. $\frac{x-1}{x^2+3x+2}}$

Step-by-step explanation:

The given expression is;

$\frac{x}{x^2+3x+2}-\frac{1}{(x+2)(x+1)}$

This is the same as;

$\frac{x}{(x+2)(x+1)}-\frac{1}{(x+2)(x+1)}$

The denominators are the same.

Subtract the numerators and write one denominator;

$\frac{x-1}{(x+2)(x+1)}}$

Rewrite to get;

$\frac{x-1}{x^2+3x+2}}$

What are the zeros in the function f(x)=(2x+6)(x-4)

Shtirlitz [24]

Hello from MrBillDoesMath!

Answer:

x = -3, 4

Discussion:

The zeroes of f(x) are the x values where

2x + 6 = 0 => x = -3

and

x - 4 = 0 => x = 4

Thank you,

MrB
