Binomial Square | (x+y)^2=x^2+2xy+y^2 (x-y)^2=x^2-2xy+y^2 |
The image of the parabola y=ax^2 under translation Thk, | is the parabola with the equation y-k=a(x-h)^2 |
The graph of y=(ax^2)+(bx)+c | is a parabola congruent to y=ax^2 |
Quadratic Formula | x= negative b plus/minus the square root of b^2 minus 4ac all over 2a |
when a doesn't equal zero,the equation(ax^2)+(bx)+c=0 has | -2 real solutions if b^2-4ac>0 -two complex conjugate solutions if b^2-4ac<0 -1 real solution if b^2-4ac=0 |
An irrational number | a real number which cannot be written as a ratio of integers |
What is the discriminant? | b^2-4ac |
