Solution for 56m^2=(m+4)(m-4) equation:


Simplifying
56m2 = (m + 4)(m + -4)

Reorder the terms:
56m2 = (4 + m)(m + -4)

Reorder the terms:
56m2 = (4 + m)(-4 + m)

Multiply (4 + m) * (-4 + m)
56m2 = (4(-4 + m) + m(-4 + m))
56m2 = ((-4 * 4 + m * 4) + m(-4 + m))
56m2 = ((-16 + 4m) + m(-4 + m))
56m2 = (-16 + 4m + (-4 * m + m * m))
56m2 = (-16 + 4m + (-4m + m2))

Combine like terms: 4m + -4m = 0
56m2 = (-16 + 0 + m2)
56m2 = (-16 + m2)

Solving
56m2 = -16 + m2

Solving for variable 'm'.

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

Add '-1m2' to each side of the equation.
56m2 + -1m2 = -16 + m2 + -1m2

Combine like terms: 56m2 + -1m2 = 55m2
55m2 = -16 + m2 + -1m2

Combine like terms: m2 + -1m2 = 0
55m2 = -16 + 0
55m2 = -16

Divide each side by '55'.
m2 = -0.2909090909
