# Theory of Equation of First Degree

To solve an Equation of First Degree follow these steps:

1. If there are parentheses and/or brackets, they are resolved with the necessary operation.

1. If there denominators, it is estimated the m.c.m. and we reduce all fractions to this common denominator.

1. Denominators are removed once they are reduced all terms to m.c.m.

1. All terms are left accompanied by “x” on one side of equality and other terms on the other side of equality.

1. Each term is simplifies the most possible.

1. Solve the unknown “x” to calculate its value.

# Theory of Second Degree Equations

To solve as second degree equation follow these steps:

1. If there are parentheses and/or brackets, they are resolved with the necessary operation.

1. If there are denominators, it is estimated the m.c.m. and we reduce all fractions to this common denominator.

1. Denominators are removed once they are reduced all terms to m.c.m.

1. Each term is simplifies the most possible.

1. All terms are left on a member and it equals to zero.

1. It is applied the following formula: Bioprofe |How to solve an ecuation| 13
