Question

Now it gets harder here’s the headaches

Answer 1

Hello!

Since the denominator of both fractions is equivalent, you can simplify both of the fraction's numerator.

5a² - 6 + -6a² + 3

-a² - 3

Then, you can factor out a negative one from the numerator.

-(a² + 3)

Therefore, your final answer is $-\frac{a^{2}+3}{b^{2}+1}$.
