Expand the expression (2x-9)(x-10)

 Exercise

$\left(2x-9\right)\left(x-10\right)$

 

Multiply the single term $x-10$ by each term of the polynomial $\left(2x-9\right)$

$2x\left(x-10\right)-9\left(x-10\right)$

 

Multiply the single term $2x$ by each term of the polynomial $\left(x-10\right)$

$2x\cdot x-20x-9\left(x-10\right)$

 

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

$2x^2-20x-9\left(x-10\right)$

 

Multiply the single term $-9$ by each term of the polynomial $\left(x-10\right)$

$2x^2-20x-9x+90$

 

Combining like terms $-20x$ and $-9x$

$2x^2-29x+90$

$2x^2-29x+90$
