How do you find the x and y intercept of a quadratic

👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.
The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

To be fair it was pretty easy. But the thing is there is factoring problems that are so hard to factor because they include really big numbers. There’s probably a video out for it, I’ll check. Thanks for this video, it helped me.

    I wish I could find a video of how to find the y intercept, when the equation is not so easily factored, or the quadratic formula gives you a negative radical.

    I have plenty of videos on solving via the quadratic formula with negative radicals, however please note that gives you the values of the x-intercepts not y

    Im a little confused at 6:44. Could you explain that to me? I don’t understand how you wrote x+4=0 and x+1=0 and made them negative at the end. Where did the negative come from? Thanks!

    when you subtract, you have to subtract from both sides using the properties of equality
