What are the solutions of the quadratic equation (x + 3) = 49,

x = - 10 x=4

Step-by-step explanation:

(x + 3) ^2 = 49

Take the square root of each side

sqrt ((x + 3) ^2) = ±sqrt (49)

(x + 3) = ±7

Separate into two equations

x+3 = 7 x+3 = -7

Subtract 3 from each side

x+3-3 = 7-3 x+3-3 = -7-3

x = 4 x=-10
