860375470 | What is a Quadratic Equation? | A quadratic equation is an equation in the form Ax^2+Bx+C=0 | 0 | |
860375471 | What is the Zero Product Property? | AB=0 if and only if A=0 or B=0 | 1 | |
860375473 | How do we complete the square? | to make x^2 +bx a perfect square, add (b/2)^2, the square of the coefficient of x this gives the perfect square x^2 + bx + (b/2)^2=(x+(b/2))^2 | 2 | |
860375474 | What is the quadratic formula? | 3 | ||
860375475 | What is the discriminant? | The discriminant of the quadratic equation ax^2+bx+c=0 is D=b^2-4ac If D>0, then the equation has two distinct real solutions if D=0, then the equation has exactly one real solution if D<0, then the equation has no real solution | 4 | |
