Answer:
0.5
Step-by-step explanation:
just plug in the number in the x place.
9x^3 + 30x^2 - 25x
step one: find the greatest common factor (GFC)
GFC=x
step two: factor out the GFC (write the GFC first. then in parentheses, divide each term by the GFC)
x(9x^3 over x + 30x^2 over x + -25x over x)
step three: simplify each term in parentheses
x(9x^2+30x-25) ...should be the answer
