How do you write # y = 2x^2 + 3x − 5# in vertex form and identify the vertex, y intercept and x intercept?
You must complete the square to solve this:
vertex form is:
to complete the square we need a leading coefficient of 1 so factor out the 2
remember the c value must be multiplied by the 2 we factored out before we add it to the left side!
finally isolate the y and it is in vertex form:
you must factor it to find the roots (x-intercepts)
So the x-intercepts are
