Answer:
The value of u are,
0.93, -12.93
Step-by-step explanation:
It is given an expression in variable u
(u + 6² + 4 = 52
<u>To find the solution of given expression</u>
(u + 6)·² + 4 = 52
(u + 6)² = 52 - 4
(u + 6)² = 48
u + 6 = √48
u + 6 = ±6.93
u = ±6.93 - 6
u = 6.93 - 6 or u = -6.93 - 6
u = 0.93 or u = -12.93
Answer: Its the 4th choice
