What is a quadratic equation? A Quadratic equation is a statement
... The term C - B2 / ( 4 A ) is the y-coordinate of the vertex point, which happens to be - D / ( 4 A ). Therefore if D = 0, the root of the quadratic equation is exactly the vertex. If D > 0 and A > 0, that means the minimum point is below x-axis and the parabola is opened upwards, then there must be ...

ELF.01.1 - Reviewing Exponent Laws
... We will use the Law of Exponents to prove that 9½ = %9. 9½ x 9½ = 9(½ + ½) = 91 Therefore, 9½ is the positive number which when multiplied by itself gives 9 The only number with this property is 3, or % 9 So what does it mean? It means we are finding the second root of 9 We can go through the same ...

... Represent and solve equations and inequalities graphically 10. Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). 11. Explain why the x-coordinates of the points where the graphs of ...
