Solve x(x+9)+12=0 by using the Quadratic Formula.

approximately -1.63 and -7.37

Step-by-step explanation:

First of all, let's expand the parenthesis by multiplying x into both of its terms.

We get the equation:

The quadratic formula looks like this

where the equation is of the form

Comparing this to our equation above,

we can see that

Let's put these values into the quadratic formula.

approximately -1.63 and -7.37

You can also choose not to approximate the square root of 33, and you'd receive the answers:

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
