To find the zeros of the polynomial \( g(x) = (x - 7)(3x - 5) \) using the Factor Theorem, we set each factor equal to zero and solve for \( x \).

  1. From the first factor: \[ x - 7 = 0 \implies x = 7 \]

  2. From the second factor: \[ 3x - 5 = 0 \implies 3x = 5 \implies x = \frac{5}{3} \]

Now, we evaluate the provided options for zeros:

  • x = −5: Not a zero
  • x = −7: Not a zero
  • x = −\frac{5}{3}: Not a zero
  • x = 7: This is a zero

Thus, the zero of \( g(x) \) is:

x = 7.
