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:
Well 120 is 1/3 of the square so the 9ft is 2/3 of the square so it is B
You must factor the second-degree polynomial to find the sides of the square. The correct factorization for this case is
x ^ 2 - 8x + 16 = (x-4) (x-4).
Therefore, the length of the side of the square is
L = (x-4).
We immediately note that 3 and 9 are multiples. Therefore, they are factorable. 9 goes into 3 three times, and 3 goes into three 1 time. Therefore, we can take out three from the whole expression to get 3(c - 3).
