5-45.

What values of $x$ will make the following equations true?

$x^2 = 64$
Answer (a):
$x = 8$ or $–8$

$(x + 1)^2 = 64$
Hint (b):
This is the same as part (a), but instead of $x$ the equation has $x + 1$ .

$( x + 1 ) ^ { 2 } - 64 = 0$
Hint (c):
Add $64$ to both sides. This problem looks very familiar now.
