Expanding the Expression: (6v² + 2v - 9)(4 - 5v)
This expression involves multiplying two binomials, one of which is a trinomial. To expand this, we'll use the distributive property (also known as FOIL - First, Outer, Inner, Last) for each term in the first binomial with each term in the second binomial.
Here's how to break it down step-by-step:
-
Distribute the 6v²:
- (6v²) * (4) = 24v²
- (6v²) * (-5v) = -30v³
-
Distribute the 2v:
- (2v) * (4) = 8v
- (2v) * (-5v) = -10v²
-
Distribute the -9:
- (-9) * (4) = -36
- (-9) * (-5v) = 45v
-
Combine all the terms:
- 24v² - 30v³ + 8v - 10v² - 36 + 45v
-
Simplify by combining like terms:
- -30v³ + 14v² + 53v - 36
Therefore, the expanded form of (6v² + 2v - 9)(4 - 5v) is -30v³ + 14v² + 53v - 36.
