Question

(x3-2x2+3x-1 ) . (2x+3) ​

Answer 1

Respuesta:

(x3-2x2+3x-1 ) . (2x+3) ​

$=x^3\cdot \:2x+x^3\cdot \:3+\left(-2x^2\right)\cdot \:2x+\left(-2x^2\right)\cdot \:3+3x\cdot \:2x+3x\cdot \:3+\left(-1\right)\cdot \:2x+\left(-1\right)\cdot \:3$

$2x^3x+3x^3-2\cdot \:2x^2x-2\cdot \:3x^2+3\cdot \:2xx+3\cdot \:3x-1\cdot \:2x-1\cdot \:3$$2x^4+3x^3-4x^3+9x-2x-3$

$2x^4-x^3+9x-2x-3$

$2x^4-x^3+7x-3$
