2) List the factors of the third term
2) Do they add to be the second term
3) Use proper signs
1) Factorizar el MCD
Si a = 1 entonces continúa...

Steps to factor ax2 + bx + c (when a ≠ 1)
If you can't factor out the GCF...
1) Multiply outside numbers
2) Find factors of that answer that add to the middle term
3) Make fractions using the lead coefficient
4) Simplify if you can
5) Write your binomials
Si no puedes factorizar el MCD...
1) Multiplicar números externos
2) Encuentra factores de esa respuesta que se suman al término medio
3) Haz fracciones usando el coeficiente principal
4) Simplifica si puedes

Steps
Look for a GCF
Identify a, b, and c (ax2+bx+c)
Find two numbers that multiply to ac AND add to b
Draw and fill in your area model
Find the outside dimensions and write your answer
Busque un GCF
Identifica a, b, y c (ax2+bx+c)
Encuentra dos números que se multiplican por ac Y se suman a b
Dibuja y completa tu modelo de área
Encuentra las dimensiones exteriores y escribe tu respuesta
Escribe tus binomios

Steps to Factor Using the GCF
Find the GCF of the numbers (use Desmos if you need).
Find the GCF of the variables. If a variable is in EVERY term, use the one with the smallest exponent.
Write the GCF in front of parentheses.
Divide each term in the problem by the GCF (dividing the coefficients and subtracting the exponents), and write the remainder inside the parentheses.
1.Encuentra el MCD de los números (usa Desmos si lo necesitas).
2.Encuentra el MCD de las variables. Si una variable está en TODOS los términos, usa la que tiene el exponente más pequeño.
3.Escribe el MCD delante de los paréntesis.
4.Divide cada término del problema por el MCD (dividiendo los coeficientes y restando los exponentes) y escribe el resto entre paréntesis.
