4(5x+1)(5x-1) = 0
1. Take out the GCF (in this case, 4)
4(25x^2-1) = 0
2. This can be further factored. Factor the values within the parenthesis
4(5x + 1)(5x -1) = 0
Answer:
1. List the prime factors of each number
2. Multiply those factors both factors have in common. If there are no common prime factors the GCF is 1.
Step-by-step explanation:
Use the factor tree method
Answer:
39
Step-by-step explanation:
4 quarters x 4 weeks = 16 quarters
16 + 23= 39 quarters
-9 is a negative number, so plus 25, it would be 16. The minus sign and the negative sign of -10 cancel out, so it is plus 10, ending up with 26. Finally, the + and - becomes negative (positive times negative equals negative), so it is -6 and you’ll end up with a final answer of 20.
