What is 1*x^2 = ?

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

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?

a = 1, b  = 5, c = 6

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.

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

One way to solve a quadratic equation is to use the formulae I gave you.

Can you middle-term factorise a quadratic polynomial?
