Question

Multiply the polynomials
(2x - 5) (-3x^2 + 4x - 7)

Answer 1

-6x^3 + 23x^2 - 34x + 35.

Explanation:

(2x - 5) (-3x^2 + 4x - 7)

= 2x(-3x^2 + 4x - 7) - 5(-3x^2 + 4x - 7)

= -6x^3 + 8x^2 - 14x + 15x^2 - 20x + 35

= -6x^3 + 23x^2 - 34x + 35.

Answer 2

`(2x - 5)( - {3x}^(2) + 4x - 7) \\ - {6x}^(3) + {8x}^(2) - 14x + {15x}^(2) - 20x + 35 \\ - {6x}^(3) + {8x}^(2) + {15x}^(2) - 14x - 20x + 35 \\ - {6x}^(3) + {23x}^(2) - 34x + 35`
