First, simplify the (x+2)(x+2) with FOIL:
f(x)=(x^{2} +2x+2x+4)-3
Combine like terms
f(x)=x^{2} +4x+1
Then you have standard form.

Hope that helps.

Is there a way to understand inequalities better? I don't get them at all!
AlekseyPX
Ok for inequalities it's this < and > that so here's a example prob 3>2 so as my teacher used it put it "it's like the little number eats the bigger number." For negatives the one that's being eaten would be the one that's the closest to 0 so -3>-5 also alone way of doing this is to make a number line that's another way I was taught how to do these. I hope this helps you!

Which system of equations can be used to find the roots of the equation 4x^2=x^3+2x?
irina [24]
Next time, please share the answer choices.
Starting from scratch, it's possible to find the roots:

<span>4x^2=x^3+2x should be rearranged in descending order by powers of x:

x^3 - 4x^2 + 2x = 0.  Factoring out x:  </span>x(x^2 - 4x + 2) = 0

Clearly, one root is 0.  We must now find the roots of (x^2 - 4x + 2):

Here we could learn a lot by graphing.  The graph of y = x^2 - 4x + 2 never touches the x-axis, which tells us that (x^2 - 4x + 2) = 0 has no real roots other than x=0.  You could also apply the quadratic formula here; if you do, you'll find that the discriminant is negative, meaning that you have two complex, unequal roots.

When a shape is rotated, it must be rotated around a point.

<em>To determine the location of the new triangle, Sonja must subtract (5,-1) from the coordinates of the original triangle, before rotating by </em>90^o<em>.</em>

<em />

From the question, we have:

C = (5,-1) --- the center of rotation

Let the vertices of the triangle be (x,y).

First, she must subtract the coordinates of the center of rotation from the vertices of the triangle.

This gives:

(x,y) \to (x - 5, y + 1)

Then the vertices are rotated by 90^o

<u />

<u>The rule of </u>90^o<u> rotation is:</u>

(x,y) \to (-y,x)

So, we have:

(x - 5,y + 1) \to (-y - 1,x - 5)

From the attachment, the coordinates of the triangle are: (0,2), (0,5) and (4,2)

After rotation, the coordinates are calculated as follows:

(0,2) \to (-2-1,0-5) \to (-3,-5)

(0,5) \to (-5-1,0-5) \to (-6,-5)

(4,2) \to (-2-1,4-5) \to (-3,-1)

Hence, the coordinates are: (-3,-5), (-6,-5) and (-3,-1)
