Question

Simplify the expression 6m^3-16m62+15m-40/2m^2+5

Answer 1

-16 m^62 + 6 m^3 - (40 m^2)/2 + 15 m + 5
The gcd of 40 and 2 is 2, so 40/2 = (2×20)/(2×1) = 2/2×20 = 20:
-16 m^62 + 6 m^3 - 20 m^2 + 15 m + 5
Factor -1 out of -16 m^62 + 6 m^3 - 20 m^2 + 15 m + 5:
Answer: -(16 m^62 - 6 m^3 + 20 m^2 - 15 m - 5)
