How do i complete a quadratic equation? i am currently doing revision for an exam and can't remember how to complete these (ex: )

The quadratic equation is:

Ignore the "A", I can't get rid of it.

ax² + bx + c = 0 That's where you find/get a, b, and c

With that example

a= 4

b = -2

c = -3

Now we plug it into the equation

(Again ignore the A)

I think you can factor out the 2

Your answers:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
