Respuesta :
x=-3
x=-11
because
x(x+14)=-33
so if x = -11 it will be 3*-11
and if x= -3 it will be -3*11
Answer:
x = -3, -11
Step-by-step explanation:
First, factor
Get all the terms on one side by adding 33 to both sides:
[tex]x^2 + 14x + 33 = 0[/tex]
now, you want to find two numbers that add up to 14 and multiply to 33.
those numbers would be 3 and 11.
so you can then make it:
[tex](x + 3)(x+11)=0[/tex]
you know that either x + 3 or x + 11 = 0,
so you can say:
x + 3 = 0
x = -3
ork
x + 11 = 0
x = -11
so x = -3, -11.
