A quadratic equation is an equation of the form where a, b, and c are real numbers and a ≠ 0
The quadratic formula is : If , then The quadratic formula is: If , then  a = 1, b = 3, and c = −7 The quadratic formula is : If , then  a = 2, b = -5, and c = 3  The solutions are rational . We
could have factored .

If , then  a = 3, b = -5, and c = 1 If , then  a = 2, b = -4, and c = -1 If , then  a = 1, b = -2, and c = -10 The quadratic formula is : If , then The sum of the two solutions will always be The product of the two solutions will always be x2 – 5x – 14 = 0
x = 7 or x = – 2
7 + (-2) = 5
7 (-2) = -14

The sum of the two solutions will always be The product of the two solutions will always be 8x2 + 14x + 3 = 0.
(4x + 1)(2x + 3) .  Prev Next
