x^2+ 9x + 18 = 0 x = ? is what?

Question

How do you figure this? I don't get this. I have 4 choices to choose from. My initial choice was wrong. {-3, -6}...

{-2, -9}

...{-1, -18}

...{-2, 9}

Answer 1

x^2+ 9x + 18 = 0
(x+6)(x+3)

x= -6 or x = -3

{-2, -9}, {-1, -18},{-2, 9} are wrong. your initial choice was good so go along with the initial one

Answer 2

simplest thanks to remedy this issue is to element x^ 2 – 9x + 18 = 0 this gives: (x-6)(x-3) = 0 { which resources x^2 - 3x - 6x + 18} Use the most of 0 products: if ab = 0, both a, b, or both should be equivalent to 0. for that reason (x-6) = 0 , or (x-3) = 0 x = 6 or 3 *Plug both numbers (one on the time) examine.

Answer 3

x^2+ 9x + 18 = 0
Find factors of the constant (18)
Constant does not have a pronumeral.

In this case, 3 and 6 are the factors
(x+6)
(x+3)
(x+6)(x+3) = 0
because
x^2+3x+6x+18 = 0
x^2+9x+18 = 0
Now, go back,
(x+6)(x+3) = 0
x+6=0
or
x+3=0
Hence, x = -6 or x=-3

Answer 4

factorise the equation ... you will get (x+3)(x+6)
therefore either x=-3 or x= - 6
when x = -3
y=0 and when x = - 6 , y = - 10

therefore, the answer = (-3, 0) , (-6, -10)

Answer 5

(x + 9) (x + 2)

Answer 6

x^2 +3x +6x +18=0
(x+3)(x+6)=0
x+3=0 ,,,,,,,,,x1= -3
x+6=0 ,,,,,,,, x2= -6
.

Answer 7

It's (x+6)(x+3)

x=-6 and x=-3

Your initial answer was right, who told you it was wrong?

..zak ur answer is very wrong

Answer 8

(x + 3).(x + 6) = 0
x = - 3, x = - 6 IS CORRECT
