Question

Which statements are true

Answer 1

Answer:

A, B and C (close examination)

Step-by-step explanation:

A. 15m3 - 6m = 3m(5m2 - 6m)

• m = 0 or m = 1/3

B. 40m6-4=4(10m6-1)

• 0 = 0
• All real numbers are solutions

C. 6m2+18m=6m2(1+3m)

• m = 0 or m = 1 or m = -1

D. 32m4+12m3(8m+3)

• 128m4 + 36m3

This is tough one but I will explain this problem by close examination:

The problem is looking for an equation that have the variable m by itself

D is out of the picture because the equations does not have m by itself

Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)

By close examination, The answer are A, B, and C.
