Expand the expression (5u-1)(4u+2)

 Exercise

$\left(5u-1\right)\left(4u+2\right)$

 

Multiply the single term $4u+2$ by each term of the polynomial $\left(5u-1\right)$

$5u\left(4u+2\right)-\left(4u+2\right)$

 

Multiply the single term $5u$ by each term of the polynomial $\left(4u+2\right)$

$20u\cdot u+10u-\left(4u+2\right)$

 

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

$20u^2+10u-\left(4u+2\right)$

 

Multiply the single term $-1$ by each term of the polynomial $\left(4u+2\right)$

$20u^2+10u-4u-2$

 

Combining like terms $10u$ and $-4u$

$20u^2+6u-2$

$20u^2+6u-2$
