Step-by-step explanation:
18x and 6y, though i can't see the operation between, can be factored by dividing out a 6. 6 is the greatest common factor, as it's a multiple of 18.
for 18x + 6y: 6(3x + y) is the factored form. if your symbol is subtraction, it's basically the same, you just change the sign.

Step-by-step explanation:
The factorisation of 49b^2 - 81 is (7b - 9)(7b + 9). This is because 49 and 81 are the squares of 7 and 9 respectively, so these must be multiplied together. b^2 is b x b. Finally, it must be -9 and +9 to make -81, because when the signs are the same the result is a positive number
