Question

multiplicar los siguientes polimios
1.(2a-b-c) (2a-b+c)

2.(x3-2x²+3x1) (2x+3)
​

Answer 1

Explicación paso a paso:

1.(2a-b-c) (2a-b+c)

$= 4 {a}^{2} - 2ab + 2ac - 2ab + {b}^{2} - bc - 2ac + bc - {c}^{2}$

$= 4 {a}^{2} + {b}^{2} - {c}^{2} - 4ab$

2.(x3-2x²+3x1) (2x+3)

$= 2 {x}^{4} + 3 {x}^{3} - 4 {x}^{3} - 6 {x}^{2} + 6 {x}^{2} + 9x$

$= 2 {x}^{4} - {x}^{3} + 9x$
