Question

Multiply. (2x+3) (x^2-x-5) ​

Answer 1

Answer:

2x^3 + x^2 - 13x - 15

Step-by-step explanation:

( 2x + 3 ) ( x^2 - x - 5 )

= 2x ( x^2 - x - 5 ) + 3 ( x^2 - x - 5 )

= 2x^3 - 2x^2 - 10x + 3x^2 - 3x - 15

= 2x^3 - 2x^2 + 3x^2 - 10x - 3x - 15

= 2x^3 + x^2 - 13x - 15

Therefore, ( 2x + 3 ) ( x^2 - x - 5 ) = 2x^3 + x^2 - 13x - 15
