Expand the expression (x-6)(2x+4)

 Exercise

$\left(x-6\right)\left(2x+4\right)$

 

Multiply the single term $2x+4$ by each term of the polynomial $\left(x-6\right)$

$x\left(2x+4\right)-6\left(2x+4\right)$

 

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

$2x\cdot x+4x-6\left(2x+4\right)$

 

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

$2x^2+4x-6\left(2x+4\right)$

 

Multiply the single term $-6$ by each term of the polynomial $\left(2x+4\right)$

$2x^2+4x-12x-24$

 

Combining like terms $4x$ and $-12x$

$2x^2-8x-24$

$2x^2-8x-24$
