Answer:

Step-by-step explanation:
Factorise the denominators of both fractions
x² - 9 and x² - 4 are both differences of squares and factor as
x² - 9 = (x - 3)(x + 3) and x² - 4 = (x - 2)(x + 2), thus express as
× 
Cancel the factors (x + 3) and (x + 2) from the numerators/denominators of both fractions leaving

Answer:
c = 9
Step-by-step explanation:
9c - 10 = 2c + 53

7c = 63
c = 9
Answer:
C) 2 (2x + 3) (3x + 1)
Step-by-step explanation:
12x² + 22x + 6
2 ( 6x² + 11x + 3 )
2 [ 6x² + 9x + 2x + 3 ]
2 [ 3x ( 2x + 3 ) + 1 ( 2x + 3 ) ]
2 ( 2x + 3 ) ( 3x + 1 ) ⇒ C
Three million, one hundred and fifty two thousand, three hundred and eight.
