Re: Quadratic Equations
Can we say that the coefficient of x^2 in x^2 is 1, then?

Re: Quadratic Equations
Well, it is.
Is x^2+5x+6 of that form?
Compare x^2+5x+6 with the ax^2 + bx + c form?
What is the value of a, b and c in this case?

Re: Quadratic Equations
a = 1, b = 5, c = 6

Re: Quadratic Equations
Okay let me write down the formula here!
What is the value of a,b and c in this equation: x^2 +5x+6 =0?
Now plug the values in these two formulae and simplify.

Re: Quadratic Equations
Use the two formulae and substitute a=1, b=5, c =6 in them

Re: Quadratic Equations
That is very good!
Please try solving the same equation as taught in school by hand. Do your answers match?

Re: Quadratic Equations
One way to solve a quadratic equation is to use the formulae I gave you.
Can you middle-term factorise a quadratic polynomial?

Re: Quadratic Equations
David, I recommend you to read every topic on quadratic equations from mathisfun.com. I see you don't know about it. It is very much required in mathematics. Please do it quickly.
