Multiply: (3x - 8)(2x² + 4x - 9) --> multiply 3x by the three values in the back, and repeat with -8 --> 6x³ + 12x² - 27x - 16x² - 32x + 72
Simplify + order by power of x: 6x³ - 4x² - 59x + 72
Coefficient: value of the number before the xᵃ
Coefficient of: x³ --> 6x³ --> 6
x² --> -4x² --> -4
x¹ --> -59x --> -59
Constant --> x⁰ --> 72 --> 72
