Use distributive property: a(b +/- c) = ab +/ ac.

(x - 9)(x + 2) = (x)(x) + (x)(2) - (9)(x) - (9)(2) = x² + 2x - 9x - 18

= x² -7x -18

The answer is: <u>2(k2−4k)(2c+5)</u>

✿————✦————✿————✦————✿

Step:

* Consider 2ck2+5k2−8ck−20k. Do the grouping 2ck2+5k2−8ck−20k=(2ck2+5k2) +(−8ck−20k), and factor out k2 in the first and −4k in the second group.

* Factor out the common term 2c+5 by using the distributive property.

* Rewrite the complete factored expression.
