Expand the expression (3x^5+3x^3)(3x+1)

 Exercise

$\left(3x^5+3x^3\right).\left(3x+1\right)$

 

Multiply the single term $3x+1$ by each term of the polynomial $\left(3x^5+3x^3\right)$

$3x^5\left(3x+1\right)+3x^3\left(3x+1\right)$

 

Multiply the single term $3x^5$ by each term of the polynomial $\left(3x+1\right)$

$9x\cdot x^5+3x^5+3x^3\left(3x+1\right)$

 

When multiplying exponents with same base you can add the exponents: $9x\cdot x^5$

$9x^{6}+3x^5+3x^3\left(3x+1\right)$

 

Multiply the single term $3x^3$ by each term of the polynomial $\left(3x+1\right)$

$9x^{6}+3x^5+9x\cdot x^3+3x^3$

 

When multiplying exponents with same base you can add the exponents: $9x\cdot x^3$

$9x^{6}+3x^5+9x^{4}+3x^3$

$9x^{6}+3x^5+9x^{4}+3x^3$
