Simplify
Solving (1):
Factorize the numerator and the denominator
Factor out x+2 at the numerator
Express x^2 - 9 as difference of two squares
Expand the denominator
Factorize
Cancel out same factors
Hence:
Solving (2):
Expand the numerator and factorize the denominator
Factorize the numerator
Factor out x - 2
Cancel out x - 2
Hence:
Solving (3):
Express x^2 - 9 as difference of two squares
Factorize all:
Cancel out x + 3 and 3 + x
Express as
Hence:
Solving (4):
Expand x^2 - 6x + 9 and factorize 5x - 15
Factorize
Cancel out x - 3
Change / to *
Express as
Hence:
Solving (5):
Factorize the numerator and expand the denominator
Factor out x - 1 at the numerator and factorize the denominator
Express x^2 - 1 as difference of two squares and factor out x - 1 at the denominator
Hence:
Solving (6):
Factorize:
Divide by 3x
Hence:
Solving (7):
Change / to *
Expand
Factorize
Cancel out x - 2 and x - 1
Cancel out x
Hence:
