2x^2 + 8x + 3 = 0
You cannot because you do not have an equation but an expression. There is no equals sign in the expression that is given.
the value of
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
One add one is 2, or better put, one plus one equals two. This is what it looks like in equation form: 1+1=2.
If you are looking for the slop intercept form it is: y = -3/2x + 8.5 The x isn't in the denominator here but you can put it in the numerator.
-7/5 For equations in Standard Form (Ax + By = C), slope equals -A/B. Or you could put the equation in Slope-Intercept form (y = mx + b) by solving for y and then finding the slope (m).
There is no solution. There is no number that can be put in place of 'x' that can make that statement true.
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
If you put an 'equals' sign ( = ) between the 'By' and the 'Cz', you have the generic equation for any straight line in 3-dimensional Cartesian coordinates.
