Equations…

Posted by ricardogm on 30th November 2017

 

Hi

1. First of all, check the equations from last days using this page of Symbolab.

2. Now solve these equations in your notebook and check the solutions with Symbolab.

a) x4 − 10x2 + 9 = 0

b) Biquadratic Equation Exercise

c) x4 − 61x2 + 900 = 0

d)Radical Equation Exercise

e) Radical Equation Exercise

f) Radical Equation Exercise

g) Nonlinear System of Equations

h) Nonlinear System of Equations

Ecuaciones con radicales

Posted by ricardogm on 26th November 2017

Muy buenas

1. Para empezar, resuelve en tu libreta estas tres acuaciones y corrigelas con Symbolab.

a) ecuación

b) ecuación

c) ecuación

2. Ahora continuamos con ecuaciones con radicales (ecuaciones irracionales). Aquí tenéis un pequeño repaso a la teoría.

3. A practicar:

a)ecuación

b)ecuación

c) ecuación

d) ecuación

e)  ecuación

4. Corrige con Symbolab.

Factorizar y simplificar

Posted by ricardogm on 19th November 2017

 

Muy buenas

1. Ejercicios sobre factorización. Se corrigen ellos solitos.

2. Factoriza los polinomios que aparecen en estas ecuaciones. Corrigelos con Symbolab.

3. Lo mismo que has hecho para factorizar sirve para resolver las ecuaciones. Las raíces del polinomio son soluciones de la ecuación P(x)=0. En este Geogebra se ve clarito:

4. Unos ejercicios sencillos sobre fracciones algebraicas. Hay que factorizar numerador y denominador y luego simplificar. Piensa en los gatinos, tan monos.

Algebraic fractions

Posted by ricardogm on 16th November 2017

 

Hi

1. Now it’s time for practice a bit with algebraic fractions (AKA rational expressions). Solve these in your notebook and check them with Symbolab.

a) Simplify:

Algebraic Fraction Exercise

Algebraic Fraction Exercise

Algebraic Fraction Exercise

Algebraic Fraction Exercise

Algebraic Fraction Exercise
b) Calculate and simplify: (HINT: before multiplying, factor everything, and simplify as much as possible)

Algebraic Fraction Exercise

Algebraic Fraction Exercise

Algebraic Fraction Exercise

Algebraic Fraction Exercise

And the solutions are here.

Next week we are going to learn to add and substract fractions:

Ruffini’s rule doesn’t rule all

Posted by ricardogm on 9th November 2017

Hi

Today we are going to use the quadratic formula to factor second degree polynomials. Sometimes, when you are using ruffini, you factor until you get a second degree polynomial. If this polynomial doesn’t have integer roots, you are not going to find them, but using the famous formula for second degree equations, you can get to them.

1. Use Symbolab to correct the exercises from yesterday. Call me if something doesn’t match.

2. Now try to factor these polynomials. In some of them you are going to need this method. Do it in your notebook, and use Symbolab to check your answers.
