Question

3(x-1)^2 =27
Solve quadratic with square roots

Answer 1

Hi! So this question is worded funny... but it's really just asking you to solve for x in the easiest way possible.

Answer 2

I think the answer is x=2

Answer 3

Nope, but a good guess. The easiest approach would be to solve using algebra. What would your first step be if that is the case?

Answer 4

Here's a hint.... If you first divided both sides by 3, then would it be possible to take the square root of both sides?

Answer 5

yeah

Answer 6

3(x+1)^2=27
(x+1)^2=9
(x+1)=9^1\2
x+1=3
x=3-1
x=2
