Question

Determine the solution set of (x - 3)2 = 49. {6, -8} {4, 10} {10, -4}

Answer 1

Answer:

{10, -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

Add 3 to each side

x-3+3 = 3±7

x =  3±7

x = 3+7   and x = 3-7

x = 10        x = -4
