So lets say I have the quadratic expression x squared plus 10x plus 9. Khan Academy is a nonprofit with the mission of providing a free world-class education for anyone anywhere. In this case in all of the examples well do itll be x.
And so you get on the left-hand side you have s is equal to negative 5.
It may have the same vertex and zeros but the y intercept is completely different and in fact the entire curve is less divergent. There are multiple techniques for example solving by factoring by quadratic equation etc. -b b²-4ac 2a. Rewrite the equation by completing the square.
