Solve the product (d^4-3)(d^4+4)

 Exercise

$\left(d^4-3\right)\left(d^4+4\right)$

 

Multiply the single term $d^4+4$ by each term of the polynomial $\left(d^4-3\right)$

$\left(d^4+4\right)d^4-3\left(d^4+4\right)$

 

Multiply the single term $d^4$ by each term of the polynomial $\left(d^4+4\right)$

$d^4\cdot d^4+4d^4-3\left(d^4+4\right)$

 

When multiplying exponents with same base we can add the exponents

$d^{8}+4d^4-3\left(d^4+4\right)$

 

Multiply the single term $-3$ by each term of the polynomial $\left(d^4+4\right)$

$d^{8}+4d^4-3d^4-12$

$d^{8}+4d^4-3d^4-12$
