(4m-a)(4m+a)=

Solution for (4m-a)(4m+a)= equation:

Simplifying
(4m + -1a)(4m + a) = 0

Reorder the terms:
(-1a + 4m)(4m + a) = 0

Reorder the terms:
(-1a + 4m)(a + 4m) = 0

Multiply (-1a + 4m) * (a + 4m)
(-1a * (a + 4m) + 4m * (a + 4m)) = 0
((a * -1a + 4m * -1a) + 4m * (a + 4m)) = 0

Reorder the terms:
((-4am + -1a2) + 4m * (a + 4m)) = 0
((-4am + -1a2) + 4m * (a + 4m)) = 0
(-4am + -1a2 + (a * 4m + 4m * 4m)) = 0
(-4am + -1a2 + (4am + 16m2)) = 0

Reorder the terms:
(-4am + 4am + -1a2 + 16m2) = 0

Combine like terms: -4am + 4am = 0
(0 + -1a2 + 16m2) = 0
(-1a2 + 16m2) = 0

Solving
-1a2 + 16m2 = 0

Solving for variable 'a'.

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

Add '-16m2' to each side of the equation.
-1a2 + 16m2 + -16m2 = 0 + -16m2

Combine like terms: 16m2 + -16m2 = 0
-1a2 + 0 = 0 + -16m2
-1a2 = 0 + -16m2
Remove the zero:
-1a2 = -16m2

Divide each side by '-1'.
a2 = 16m2

Simplifying
a2 = 16m2

Take the square root of each side:
a = {-4m, 4m}
