3x(x + 6) = -10 Enter your solution in the exact, most simplified form. If there are two solutions, write the answer using the ± symbol. DESCRIBE AND JUSTIFY THE METHODS YOU USED TO SOLVE THE QUADRATIC EQUATION!

Step-by-step explanation:

Expand it:

Add 10 to both sides:

Divide both sides by 3:

Find a, b for

It’s

So, inserting it leads to:

Subtract b from both sides:

Apply square root to both sides and consider the two solutions:

Subtract 3 from both sides and you get

hi, i am not sure about this one but i think its d,

hope this !

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.
