Write this polynomial in standard form

Answer:
[tex]- 4x {}^{3 } + 8x {}^{2} - 5x + 12 = 0[/tex]
Step-by-step explanation:
The Standard Form Of Cubic Polynomial Is
[tex] = ax {}^{3} + bx {}^{2} + cx + d = 0[/tex]
so,
the standard form of given polynomial is
[tex] - 4x {}^{3 } + 8x {}^{2} - 5x + 12[/tex]
