Question

Solve for x.
x^2 - 12x + 36 = 0

Answer 1

Answer:
`x=6`

Factor left side of equation

`(x-6)(x-6)=0`

Set factors equal to 0

`x-6=0`
`or`
`x-6=0`

`x=6`

Answer 2

`{x}^(2) - 12x + 36 \\ {x}^(2) - 6x - 6x + 36 \\ x(x - 6) - 6(x - 6) \\ (x - 6)(x - 6) \\ \\ \\ x - 6 = 0 \\ x = 6 \\ \\ x - 6 = 0 \\ x = 6`
