Question

(2m-5) Expand for 8 class

Answer 1

(2m - 5)³

Write the expression out in full.

(2m - 5)(2m - 5)(2m - 5)

We can multiply the first two brackets first.

(4m² - 20m + 25)(2m - 5)

Now multiply the remaining brackets.

8m³ - 20m² - 40m + 50m + 100m - 125

Finally, combine the similar terms to get the answer.

8m³ - 20m² +90m - 125
