hi
because it lead to mathematical nonsense
3x-7 = 3x+5
3x-7 -3x-5 = 0
-7-5 = 0
-12 =0
-12 = 0 is just not possible, so 3x-7 = 3x +5 has no solution.
Step-by-step explanation:
cubing both sides (p+1)^3= (7)^3
=> p^3+1/p^3+ 3(p+1/p) = 343
=> p^3+ 1/p^3 + 3(7)= 343
=> p^3+1/p^3= 343-21
=> p^3+1/p^3= 322
hope it helps
Answer:
B
Step-by-step explanation:
f(x) = x²+49 , rewrite the equation
x² +7² =0 , to find the roots make f(x) =0 and subtract 7² from both sides
x² = -7², square root both sides
√x² =√-7², consider √-1 =i
x= ±7i
the roots are -7i and 7i
Answer:
I think it's C. , but I'm not too sure . You should double check to see if it's correct.
