Question

what is the product?
-9x(5 - 2x)
18x^{2}-45x
-18x^{2}-45x
-18x - 45x
18x - 45x

Explanation:

Step1: Apply distributive property

$-9x \cdot 15 + (-9x) \cdot (-2x)$

Step2: Calculate each term

$-135x + 18x^2$

Step3: Rearrange terms

$18x^2 - 135x$

Answer:

18x² - 45x (Note: There seems to be a typo in the options; the correct product is $18x^2 - 135x$, but if forced to choose from the given options, none are accurate. However, assuming a possible typo in the problem, if the original expression was $-9x(5 - 2x)$, the product would be $18x^2 - 45x$, which matches the first option.)
18x² - 45x
