Quadratic Equations Flashcards
1
Q
General form of a Quadratic Equation
A
ax^2 + bx + c
2
Q
Zeroes or Roots of a Quadratic Equation.
A
x = α is a solution of
the quadratic equation, or that α satisfies the quadratic equation. When α is put in place of x, and the equation sums up to ‘zero’ then α is the root (or zero) of the quadratic equation.
3
Q
A quadratic equation can be solved by using?
A
Splitting the Middle Term.
4
Q
Quadratic formula
A
(-b ± sqrt b^2 - 4ac)/2a
5
Q
if b^2 - 4ac is > 0
A
Then the equation has two real roots.
6
Q
if b^2 - 4ac is = 0
A
Then the equation has two equal roots.
7
Q
if b^2 - 4ac is < 0
A
Then the equation has two imaginary roots.
