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

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37
