Answer:
x^2 + x-72=0
Step-by-step explanation:
x(x+1) =72
Distribute
x^2 +x = 72
Subtract 72 from each side
x^2 +x - 72 = 0
Now this is the equation we can factor
Answer:
11
Step-by-step explanation:
This is a difference of squares and therefore can be written as (76-1)(76+1)=(75)(77).
So lets look at the factors....
75=3(25)=3(5)(5)
77=7(11)
The biggest prime factor is therefore 11.
Identities used:
Difference of squares a^2-b^2=(a-b)(a+b)
The answer is -43
B=-1-7(6)
B=-1-42
B=-43
