Example 2 Assuming that the graph of y = x2 – 3x + 1 has been drawn, find the equation of the line which
should be drawn to solve the equation:
x² - 4x +3=0

Y is equals to x to the power of 2 -3x+1 It’s not 2x incase you don’t get it please help!!ʕ•ᴥ•ʔ

y=x-2

Step-by-step explanation:

If you have drawn the graph of .

To determine the equation of the line which  should be drawn to solve the equation:  x² - 4x +3=0

Simply carry out the subtraction:

The equation of the line which should be drawn is: y=x-2

What this means is simply:

If

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
