how do I get this equation into x-intercept form??

Question

Put the equation 2x^2 (squared) - 2x - 40 into standard form

Answer 1

factor a 2 out of the first two terms
2(x^2-x)-40
complete the square
2(x^2-x+1/4)-40-1/2
2(x-1/2)^2-40.5
the vertex is at x=.5 y= -40.5

Answer 2

that is it: y=2x^2-2x-40 This is a parabola, but graph it on your graphing calculator
