Derive the quadratic formula from the standard form (ax² + bx + c = 0) of a quadratic equation by
following the steps below.
1. divide all terms in the equation by a.
2. subtract the constant (the term without an x) from both sides.
3. add a constant (in terms of a and b) that will complete the square.
4. take the square root of both sides of the equation.
5. solve for x.
Answers: 2
(now add the constant in terms of a and b)
(now simplify the fractions on the right side)
(now just put the b^2 in front)
(you can square root the bottom bit of the fraction fully)
(now simplify)
(note: it should be a plus or minus sign infront of the squareroot, not just a plus sign -it's just that i can't write it in )

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
