Answer:
Explanation:
Factor x² + 3x, and x²+ x - 6
To add or subtract expressions, we expand them to make their denominators the same, LCM of x(x+3) and (x-2)(x+3) is x(x-2) (x+3).
Multiply
and
Here,
and
have the same denominators, we will subtract them by subtracting their numerators:
*Multiply (x+6)(x-2)-5x:
Combine like terms: x² - 2x + 6x - 12 - 5x
Now, factor expressions that are not already factored:
Expand:
