Question

What number should be subtracted from $$2x^3 - 5x^2 + 5x$$, so that the resulting polynomial has $$(2x - 3)$$ as a factor?

Options

• 2

• –2

• –3

• 3

Answer 1

3

Explanation:

At the zero $$x = \frac{3}{2}$$, the original polynomial equals $$3$$; subtracting $$3$$ makes the new value zero.
