Question

(x+2)(x-1)(x-3)

substitute the formula​​

Answer 1

Answer

$x^3-2x^2-5x+6$

Step-by-step explanation

$\left(x+2\right)\left(x-1\right)\left(x-3\right)$

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

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

$=x^2x-3x^2+xx-3x-2x+2\cdot \:3$

$=x^3-2x^2-5x+6$

Answer 2

Step-by-step explanation:

=> (x-1)(x-2)(x-3)

=> (x²-3x+2)(x-3)

=> (x³-3x²-3x²+9x+2x-6)

=> (x³-6x²-11x-6)
