G=4ca-3ba <=> G=a(4c-3b)
<=> a=G/(4c-3b)
One of the product rules for exponents was used.

Or, you can consider that the definition of an exponent and the associative and commutative properties of multiplication were used.
Answer:
x = -2/3, 0, 3/4
Step-by-step explanation:
The zeros of the polynomial are the solutions or roots or x-intercepts of the function. To find them, use the zero product property to solve for x. Use the property by setting each factor equal to 0.
x = 0 4x-3=0 3x+2 = 0
x = 3/4 x = -2/3
The answer is c to your question
