Question

  1. use algebra tiles to find $(3x^{2}+9x)+(6x^{2}+10x + 4)$. 2) combine like terms. for example, write 3 instead of $1 + 1 + 1$.

Explanation:

Step1: Agrupar términos semejantes de $x^2$

$3x^2 + 6x^2 = (3+6)x^2 = 9x^2$

Step2: Agrupar términos semejantes de $x$

$9x + 10x = (9+10)x = 19x$

Step3: Agrupar términos constantes

$0 + 4 = 4$

Step4: Sumar los resultados anteriores

$9x^2 + 19x + 4$

Answer:

$9x^2 + 19x + 4$
