The Quadratic Formula
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
This expression gives two answers.
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
x^{2} – 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
8x^{2} + 14x + 3 = 0.
(4x + 1)(2x + 3) .
