(m^2+5m+3)-(m^2-5m-3)=

Solution for (m^2+5m+3)-(m^2-5m-3)= equation:

Simplifying
(m2 + 5m + 3) + -1(m2 + -5m + -3) = 0

Reorder the terms:
(3 + 5m + m2) + -1(m2 + -5m + -3) = 0

Remove parenthesis around (3 + 5m + m2)
3 + 5m + m2 + -1(m2 + -5m + -3) = 0

Reorder the terms:
3 + 5m + m2 + -1(-3 + -5m + m2) = 0
3 + 5m + m2 + (-3 * -1 + -5m * -1 + m2 * -1) = 0
3 + 5m + m2 + (3 + 5m + -1m2) = 0

Reorder the terms:
3 + 3 + 5m + 5m + m2 + -1m2 = 0

Combine like terms: 3 + 3 = 6
6 + 5m + 5m + m2 + -1m2 = 0

Combine like terms: 5m + 5m = 10m
6 + 10m + m2 + -1m2 = 0

Combine like terms: m2 + -1m2 = 0
6 + 10m + 0 = 0
6 + 10m = 0

Solving
6 + 10m = 0

Solving for variable 'm'.

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

Add '-6' to each side of the equation.
6 + -6 + 10m = 0 + -6

Combine like terms: 6 + -6 = 0
0 + 10m = 0 + -6
10m = 0 + -6

Combine like terms: 0 + -6 = -6
10m = -6

Divide each side by '10'.
m = -0.6

Simplifying
m = -0.6
