Expand the expression (x+3)(3x-5)

 Exercise

$\left(x+3\right)\left(3x-5\right)$

 

Multiply the single term $3x-5$ by each term of the polynomial $\left(x+3\right)$

$x\left(3x-5\right)+3\left(3x-5\right)$

 

Multiply the single term $x$ by each term of the polynomial $\left(3x-5\right)$

$3x\cdot x-5x+3\left(3x-5\right)$

 

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

$3x^2-5x+3\left(3x-5\right)$

 

Multiply the single term $3$ by each term of the polynomial $\left(3x-5\right)$

$3x^2-5x+9x-15$

 

Combining like terms $-5x$ and $9x$

$3x^2+4x-15$
