Question

Find the point(s) of intersection of the parabola with equation y = x2 - 5x + 4 and the line with equation y = 2x - 2

Answer 1

Note how both of these are equal to "y"

y = x^2 - 5x + 4
y = 2x - 2

or

x^2 - 5x + 4 = y = 2x - 2

now just "take out the middle man" (the y) and solve

x^2 - 5x + 4 = 2x - 2

Can you do this?

Answer 2

from quadratic equation?

Answer 3

First step is to move all the variables to one side of the equal sign.

Answer 4

ikr?

Answer 5

x^2 - 5x + 4 = 2x - 2 add 2 to both sides
x^2 - 5x + 6 = 2x subtract 2x from both sides
x^2 - 7x + 6 = 0 See if you can factor the left side (if not, use quadratic formula)

Thankss :D
