Question

Select the correct answer.

Determine the solutions to the following equation.
(1 – 4)2 = 81
O
x= -13 and 5
x= -5 and 13
x= -4 and 9
x = -9 and 4

Answer 1

Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?

If so, then the solutions are x = -5 and x = 13 .

If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.
