SOLUTION: I have an equation: 4x^2 - 24x + 27 = 0
The first part of the question requires me to complete the square so I get:
4*(x-3)^2 - 9 = 0
Using this, how can I solve x, WITHOUT us

This is to be factorized first.
=
= . So either of the factors is equal to 0. Because 0 multiplied by any number is equal to 0.
= If , then 2x = 3; x = 3/2 = 1.5
= If , then 2x = 9; x = 9/2 = 4.5
x = {1.5, 4.5} Answer.
I hope you understood this. All the best.

Add 9 to both sides of equation to get:
----- Dividing by 4
= ± ---- Taking square root of both sides of equation
= ±
x = ± ------ Adding 3 to both sides of equation
x = ±
x = ----- , or
OR
x = ----- , or
