Question

solve for d.
$d^2 - 100 = 0$
write your answers as integers or as proper or improper fractions in simplest form.
$d = \boxed{}$ or $d = \boxed{}$

Explanation:

Step1: Isolate \(d^2\)

Add 100 to both sides of the equation \(d^2 - 100 = 0\) to get \(d^2 = 100\).

Step2: Take square root

Take the square root of both sides. Remember that a square root has two solutions, positive and negative. So \(d = \pm\sqrt{100}\). Since \(\sqrt{100}=10\), we have \(d = 10\) or \(d = - 10\).

Answer:

\(d = 10\) or \(d = -10\)
