Subtract these polynomials and simplify. Enter your response in standard form. (2 - 4x9 + 3x3) - (7x + x3 - 6 + 12x4)

2 - 4x⁹ + 3x³ - (7x + x³ - 6 + 12x⁴)

= 2 - 4x⁹ + 3x³ - 7x - x³ + 6 - 12x⁴

= (2 + 6) + (-4x⁹) + (3x³ - x³) + (-7x) + (-12x⁴) grouped like terms

= 8 - 4x⁹ + 2x³ - 7x - 12x⁴ added like terms

= - 4x⁹ - 12x⁴ + 2x³ - 7x + 8 standard form

Step-by-step explanation:

(2 - 4x9 + 3x3) - (7x + x3 - 6 + 12x4)

= 2 - 4x9 + 3x3 - 7x - x3 + 6 - 12x4

= - 4x9 - 12x4 + 3x3 - x3 - 7x + 2 + 6

= - 4x9 - 12x4 + 2x3 - 7x + 8
