Work shown above! Answer to both is A
Here we are given the expression:
Now let us equate it to zero to find x first,
Now subtracting 18 from the other side,
taking square root on both sides,
So we will get two values of x as ,
Now we can write square root -1 as i,
So our factors become,
Answer:
The final factored form becomes,
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..
