[ Step One ] Distribute Parenthesis

`\bold{xx^2+x\cdot \:6x+x\left(-5\right)+\left(-4\right)x^2+\left(-4\right)\cdot \:6x+\left(-4\right)\left(-5\right)}`

[ Step Two ] Apply Addition / Subtraction Rules

Note:
`\bold{Addition \ / \ Subtraction \ Rules: \ +\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab}`

`\bold{x^2x+6xx-5x-4x^2-4\cdot \:6x+4\cdot \:5}`

[ Step Three ] Simplify
`\bold{x^2x+6xx-5x-4x^2-4\cdot \:6x+4\cdot \:5}`

`\bold{x^3+2x^2-29x+20}`
