Answer:

  • -2

Step-by-step explanation:

Given polynomial:

  • 3x⁶ - 2x⁹ + 5x - 12

Convert this into standard form, order in descending powers:

  • -2x⁹ + 3x⁶ + 5x - 12

The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.

[tex]\\ \rm\longmapsto 3x^6-2x^9+5x-12[/tex]

Write in standard form

[tex]\\ \rm\longmapsto -2x^9+3x^6+5x-12[/tex]

  • 9>6>1

-2x has greatest degree hence leading coefficient is -2.
