Question

What are the solutions of 3x2 = 18x?

x = 0, x = 6

x = 0, x = −6

x = 3, x = 6

x = 3, x = −6

Answer 1

subtract 18x from both sides first..what do you get?

Answer 2

okay one sec

Answer 3

okay wait im confused soo do the exponents first right..?

Answer 4

3x^2 = 18x
3x^2 - 18x = 0
Next, factor out 3x from both expressions on the left.

Answer 5

soo is it x=3 and x=-6..?

Answer 6

Factor first.
3x^2 - 18x = 0
3x(x - 6) = 0
Then, use the Zero Product Property which states that if two factors multiply to zero, then one or both factors are equal to zero.
So,
3x = 0 or x - 6 = 0
x = 0 or x = 6 --> Answer
