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]
