b = 3,c is constant tertm.......
Lesson 3.8 use the quadratic formula and the discriminant
All radicals must be in simplest radical form. For the following equations, match the proper values for a b and c when the equations are written in standard form.

-
x^2 + 3x= 20

In standard form:

x^2 + 3x - 20 = 0
1*x^2 + 3*x - 20 = 0

Standard form of a quadratic equation:
a*x^2 + b*x + c = 0

So a = 1, b = 3, and c = -20

-
a is coefficient of x^2

b is coefficient of x

c is constant tertm.

x^2 + 3x = 20 ==> x^2 + 3x - 20 = 0

a = 1

b = 3

c = -20

-
a=1
b=3
c= -20
