The cube of the difference of 4 times x and 9

64x³ - 432x² + 972x - 729

Step-by-step explanation:

Write the statement into an expression

(4x - 9) ³Now multiply that out ... (4x - 9) ² (4x - 9) Foil the first binomial (16x² - 72x + 81) (4x - 9) Multiply the two polynomials together 16x² (4x) - 72x (4x) + 81 (4x) + 16x² (-9) - 72x (-9) + 81 (-9) 64x³ - 288x² + 324x - 144x² + 648x - 729combine like terms ... 64x³ - 432x² + 972x - 729
