news distributive properties to multiply the polynomials -5t^3(6t^7-9t)

1 answer

To use the distributive property to multiply the polynomial \(-5t^3\) by each term in the polynomial \(6t^7 - 9t\), you will perform the following steps:

  1. Distribute \(-5t^3\) to \(6t^7\).
  2. Distribute \(-5t^3\) to \(-9t\).

Let's do the calculations:

  1. Multiply \(-5t^3\) by \(6t^7\): \[ -5t^3 \cdot 6t^7 = -30t^{3+7} = -30t^{10} \]

  2. Multiply \(-5t^3\) by \(-9t\): \[ -5t^3 \cdot (-9t) = 45t^{3+1} = 45t^{4} \]

Now, combine both results: \[ -30t^{10} + 45t^{4} \]

Therefore, the final result of multiplying \(-5t^3\) by \(6t^7 - 9t\) is: \[ -30t^{10} + 45t^{4} \]
