Expand the expression (6a+7)(11a+8)

 Exercise

$\left(6a+7\right)\left(11a+8\right)$

 

Multiply the single term $11a+8$ by each term of the polynomial $\left(6a+7\right)$

$6a\left(11a+8\right)+7\left(11a+8\right)$

 

Multiply the single term $6a$ by each term of the polynomial $\left(11a+8\right)$

$66a\cdot a+48a+7\left(11a+8\right)$

 

When multiplying two powers that have the same base ($a$), you can add the exponents

$66a^2+48a+7\left(11a+8\right)$

 

Multiply the single term $7$ by each term of the polynomial $\left(11a+8\right)$

$66a^2+48a+77a+56$

 

Combining like terms $48a$ and $77a$

$66a^2+125a+56$

$66a^2+125a+56$
