Step-by-step explanation:
x = -2.5 is a vertical line. The vertical graph of the equation is shown in the image attached below.
<h3>What is the Equation of a Vertical Line?</h3>
The slope of a vertical line is undefined, therefore, the equation of a vertical line is expressed as x = a, where a is the x-intercept.
Given x = -2.5, the equation suggests it is a vertical line, where the line intercepts the x-axis at -2.5, which is the x-intercepts.
Thus, the graph for x = 2.5 is shown in the diagram below.

Answer:
x = 3/2 or 1.5
Step-by-step explanation:
distribute 3 to the 2x and -1 by multiplying
6x - 3 = 6
add 3 to both sides to get 6x by itself and it keeps both sides equal
6x = 9
divide by 6
x = 9/6 = 3/2
x = 3/2
is the formula for calculating x1 and x2
To prove x1 + x2 = -b/a all we need to do is to express x1 and x2 from equation above
once we do we will get -2b/2a which is equal to -b/a because square root part will negate each other. one has + sign in front and other - sign
Showing that x1x2 = c/a goes similar way.
the numerator parts is actually difference of squares. after that we will have:
-b^2 -b^2 + 4ac = 4ac
in denominator we have 2a*2a = 4a^2
4ac/4aa = c/a
