Give the value of a, b, and c from the standard for of the equation (2x+1)(x-2)=0

When we expand this expression, we'll have a quadratic equation in the general form.

The general form of quadratic equations looks like this :

( a is coefficent of  , b is coefficient of x and c is the constant)

So let's expand the expression.

This how the final form of our equation :

As you can see  's coefficient (a) is 2 , x's coefficient (b) is -3 and the constant (c) is -2

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

i do not know the answer
