Answer: The given quadratic expression is:

9x² - 14x + 16

To factorize it, we can use the quadratic formula:

x = [-(-14) ± √((-14)² - 4(9)(16))] / 2(9)

Simplifying under the square root:

x = [-(-14) ± √(4)] / 18

x = [14 ± 2] / 18

x = (16/18) or x = (12/18)

Simplifying:

x = (8/9) or x = (2/3)

So the roots of the quadratic are x = 8/9 and x = 2/3. Therefore, we can factorize the quadratic expression as:

9x² - 14x + 16 = 9(x - 8/9)(x - 2/3)
