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

To find the solution of given expression

(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
