Solve the product (4m+6)(4m-9)

 Exercise

$\left(4m+6\right)\left(4m-9\right)$

 

Multiply the single term $4m-9$ by each term of the polynomial $\left(4m+6\right)$

$4m\left(4m-9\right)+6\left(4m-9\right)$

 

Multiply the single term $4m$ by each term of the polynomial $\left(4m-9\right)$

$16m\cdot m-36m+6\left(4m-9\right)$

 

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

$16m^2-36m+6\left(4m-9\right)$

 

Multiply the single term $6$ by each term of the polynomial $\left(4m-9\right)$

$16m^2-36m+24m-54$

 

Combining like terms $-36m$ and $24m$

$16m^2-12m-54$

$16m^2-12m-54$
