Answer:
(5x−3)(x−3)
Step-by-step explanation:
For a polynomial of the form
ax2+bx+c, rewrite the middle term as a sum of two terms whose product is
a⋅c=5⋅9=45 and whose sum is b=−18.
5x2−3x−15x+9
Factor out the greatest common factor from each group.
x(5x−3)−3(5x−3)
Factor the polynomial by factoring out the greatest common factor, 5x−3.
(5x−3)(x−3)
