Question

$\frac{ {y}^{2} }{y + 8} - \frac{64}{y + 8}$
how do you solve this​

Answer 1

Answer:

y - 8

Step-by-step explanation:

Since the fractions have a common denominator, subtract the numerators leaving the common denominator, that is

$\frac{y^2-64}{y+8}$ ← factor the numerator as a difference of squares

= $\frac{(y-8)(y+8)}{y+8}$ ← cancel the common factor (y + 8), leaving

= y - 8
