How do you find the intercepts for #y=2x^2-5x+2#?
(2x-+1) (x-2)
Ok so I know the picture is a little hard to read as this was done on my doodle pad.
However, here is a written expression.
First, divide a and c which would be 2 and 2. Then, find two numbers that multiply 4 and add -5 which would be -1 and -4. Next, split the middle with 2x^2-4x-1x+2.
This part's a little tricky, but hang in there :)
Ok, so factor out a 2x from the 2x^2 and a -1 from -1x+2, both answers should be (x-2)
Now this a little hard to explain, but since you used both 2x and -1 to divide 2x^2-4x-1x+2, write (2x-1).
Now your final answers should be (2x-1) (x-2)
Going further to find your x-intercepts, set each equation to zero.
2x-1=0 is x=1/2 x-2=0 is x=2
Your x intercepts are 1/2 and 2.
Hope this helped! :)

To find the intercepts for the equation y = 2x^2 - 5x + 2, you set y to 0 to find the x-intercepts, and set x to 0 to find the y-intercept.
-
To find the x-intercepts, solve the equation 2x^2 - 5x + 2 = 0 for x using factoring, the quadratic formula, or completing the square.
-
To find the y-intercept, substitute x = 0 into the equation y = 2x^2 - 5x + 2 and solve for y.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
