2.2 General Form of Quadratic Equation

General Form of Quadratic Equation
General form of a quadratic equation is
ax2 + bx + c = 0
where a, b, and c are constants and a≠0.
*Note that the highest power of an unknown of a quadratic equation is 2.

Example (Find the values of a, b and c)
Rewrite the following into the general form of a quadratic equation. Find the values of a, b, and c.
(a) (3x − 5)2 = 0
(b) (x – 8)(x + 8) = 10

Solution


(c)

n1 n+1 =3n+1 n1=( 3n+1 )( n+1 ) n1=3 n 2 +3n+n+1 0=3 n 2 +4n+1n+1 3 n 2 +3n+2=0 a=3, b=3, c=2
