Question

. Multiply the polynomials 2x and (x2-2x-1)

​

Answer 1

Answer:

${2x}^{3} - {4x}^{2} - 2x$

Step-by-step explanation:

$2x( {x}^{2 } - 2x - 1) \\ 2x \times {x}^{2} - 2x \times 2x - 2x \times 1 \\ {2x}^{3} - {4x}^{2} - 2x$

Answer 2

Answer:

2x² - 4x² - 2x

Step-by-step explanation:

Give polynomial

2x and x²-2x - 1

product = 2x (x ² - 2x - 1)

= (2x × x 2²) - (2x × 2x ) - (2x - 1 )

= 2x³ - 4x ² - 2x

therefore , the product = 2x³ - 4x² - 2x
