need to solve for x-intercepts using quadratic formula. How do I enter it?
Answer provided by our tutors
Set the quadratic equation equal to zero and that will define the x-intercepts (if the graph does intercept the x-axis, so a null answer is possible).
Some of the linear equations are best suited for the desktop Algebrator, which provides quite a few "Wizards" to simplify linear equation manipulations:
