Factor the expression over the complex numbers.<br><br><img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B18" id="TexFormula1
AleksAgata [21]

Here we are given the expression:

x^{2}+18

Now let us equate it to zero to find x first,

x^{2}+18=0

Now subtracting 18 from the other side,

x^{2}=-18

taking square root on both sides,

So we will get two values of x as ,

x=3\sqrt{-2}

x=-3\sqrt{-2}

Now we can write square root -1 as i,

So our factors become,

x=3i\sqrt{2}

x=-3i\sqrt{2}

Answer:

The final factored form becomes,

(x+3i\sqrt{2})(x-3i\sqrt{2})

Select the statements that are true about the graph.
torisob [31]

Answer:It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Step-by-step explanation:

The Y intercept of a straight line is simply where the line crosses the Y axis.

Example

Y intercept

In the above diagram the line crosses the Y axis at 1.

The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..
