Answer:
M = 7x² +21
Step-by-step explanation:
Subtract the unwanted terms on the left from both sides.
(-7x² +6x -16) + M = 6x +5
M = 6x +5 -(-7x² +6x -16)
M = 7x² +21 . . . . simplify
Answer:
x = -3, x = 0 is a extraneous solution
Step-by-step explanation:
Step 1: Cross-multiply
3x² = 4x² + 3x
Step 2: Isolate <em>x</em>'s
0 = x² + 3x
Step 3: Factor
0 = x(x + 3)
Step 4: Find roots
x = 0, -3
Step 5: Double check work
Plug in both to see if they both work. Only x = 0 should be extraneous. We now have our answer!
