F of x equals 2x^2- 3x

G of x equals x squared - 6
What is (f* g)( x)

1 answer

To find \((f \cdot g)(x)\), we need to multiply the functions \(f(x)\) and \(g(x)\) together.

Given:

  • \(f(x) = 2x^2 - 3x\)
  • \(g(x) = x^2 - 6\)

We will calculate the product \(f(x) \cdot g(x)\):

\[ (f \cdot g)(x) = f(x) \cdot g(x) = (2x^2 - 3x)(x^2 - 6) \]

Now, we can use the distributive property (or FOIL) to multiply these two polynomials:

\[ = 2x^2(x^2) + 2x^2(-6) + (-3x)(x^2) + (-3x)(-6) \]

Calculating each term:

  1. \(2x^2 \cdot x^2 = 2x^4\)
  2. \(2x^2 \cdot -6 = -12x^2\)
  3. \(-3x \cdot x^2 = -3x^3\)
  4. \(-3x \cdot -6 = 18x\)

Now, combine all these results:

\[ (f \cdot g)(x) = 2x^4 - 3x^3 - 12x^2 + 18x \]

Thus, the product \((f \cdot g)(x)\) is:

\[ \boxed{2x^4 - 3x^3 - 12x^2 + 18x} \]
