apply the quadratic formula to find the roots of the given function, and then graph the function:f(x) = x2 + 4

Weegy: f(x)=x^2-4
a=1,b=0,c=-4
x1= (0+sqrt(0+16))/2
x1=2
x2= (0-sqrt(0+16))/2
x2= -2 (More)

complete the square, and find the roots of the quadratic equation.x2 - 2/3x = 0 x = 1/2 (3-sqrt(37)) x = 1/2 (3+sqrt(37))

Weegy: x^2-(2/3)*x=0
x(x-(2/3)) = 0
so x=0 or x-(2/3)=0
- > x=0 or x=2/3

What do we do if the middle term of the quadratic equation (bx) is missing? Who wants to give the following a try?
2x2 + 1 = 0

Weegy: The syntax of quadratic equation that we are familiar with is ax^2+bx+c=0. This actually is an adfected quadratic equation.
The real form is ax^2+b=0, which is a pure quadratic equation.
2x^2+1=0
or, 2x^2=-1.
or, x^2=-1/2
or, x=sqrt(-1/2). (More)
