Answer:

X=-15

X=9

Step-by-step explanation:

I think this is how you do it

[tex](x + 3)(x + 3) - 144 \\ {x}^{2} + 3x + 3x + 9 - 144 \\ {x}^{2} + 6x - 135 \\ [/tex]

From there it's a regular quadratic

[tex] {x}^{2} - 9x + 15x - 135 \\ x(x - 9) + 15(x - 9) \\( x + 15)(x - 9) \\ x = - 15 \\ x = 9[/tex]
