Answer:

[tex]\left(x+3\right)\left(x-15\right)[/tex]

Step-by-step explanation:

Given info:

Factor completely: [tex]x^2 -12x -45[/tex]

Solve:

Break the expression to : [tex]\left(x^2+3x\right)+\left(-15x-45\right)[/tex]

Factor out x from x²+ 3x :x ( x +3 )

Factor out -15 from -15x - 45 : -15( x + 3 )

Put them together:

[tex]x\left(x+3\right)-15\left(x+3\right)[/tex]

Now factor  x + 3

Answer~: [tex]\left(x+3\right)\left(x-15\right)[/tex]
