0 = (2x − 3)(x + 1)

Answer:

Which equation is equivalent to log3(2x4 + 8x3) – 3log3x = 2log3x?

log3(–x3 + 8x2) = log3x2

–2log3(2x4 + 8x3 – x) = log3x2

log3(2x + 8) = log3x2

What are the potential solutions to the equation?

= –4 and x = 2

= –4 and x = –2

x = –2 and x = 4

= 2 and x = 4

Option

0 = 2x2 − x −3

Answer:

Which statement is true about the potential solutions to log3(2x4 + 8x3) – 3log3x = 2log3x?solutions.

Both are extraneous

Only x = –2 is an extraneous solution.

Only x = 4 is an extraneous solution.

Neither solution is extraneous.

Potential solutions are −1 and 32.

Answer:

2x − 3 = 0 or x + 1 = 0

Answer:

x + 2 = 2x2 − 1

Answer:

3log3(x + 2) = 3log3(2x2 − 1)

Answer:

Which statement is true about the potential solutions for this equation?

Both are extraneous solutions.

Only x = –1 is an extraneous solution.

Only is an extraneous solution.

Neither solution is extraneous.
