... Image 2, Equal Real Roots: A Quadratic must have 2 roots. However, in this case they are the same. This is because for Image 2 the curve only cuts the graph in 1 place. So there is only one value for x. It doesn’t go below the x-axis as if it were to it would have to come up in at a different valu ...

... don't know yet. It is usually a letter like x or y. A number on its own is called a Constant. A Coefficient is a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient) An Operator is a symbol (such as +, ×, etc) that represents an operation (ie you want to do something with t ...
