(m+d)(m-d)=

Solution for (m+d)(m-d)= equation:

Simplifying
(m + d)(m + -1d) = 0

Reorder the terms:
(d + m)(m + -1d) = 0

Reorder the terms:
(d + m)(-1d + m) = 0

Multiply (d + m) * (-1d + m)
(d(-1d + m) + m(-1d + m)) = 0
((-1d * d + m * d) + m(-1d + m)) = 0

Reorder the terms:
((dm + -1d2) + m(-1d + m)) = 0
((dm + -1d2) + m(-1d + m)) = 0
(dm + -1d2 + (-1d * m + m * m)) = 0
(dm + -1d2 + (-1dm + m2)) = 0

Reorder the terms:
(dm + -1dm + -1d2 + m2) = 0

Combine like terms: dm + -1dm = 0
(0 + -1d2 + m2) = 0
(-1d2 + m2) = 0

Solving
-1d2 + m2 = 0

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-1m2' to each side of the equation.
-1d2 + m2 + -1m2 = 0 + -1m2

Combine like terms: m2 + -1m2 = 0
-1d2 + 0 = 0 + -1m2
-1d2 = 0 + -1m2
Remove the zero:
-1d2 = -1m2

Divide each side by '-1'.
d2 = m2

Simplifying
d2 = m2

Take the square root of each side:
d = {-1m, m}
