Why does a quadratic expression have three terms if the prefix quad means four?

"Quadratic" in this sense means that the highest power used is two. This is similar to the use of "squared", for the power two. Since the highest power is two, you may need a term for the power two, a term for the power one, and a term for the power zero (the constant term).
For comparison, a "cubic" expression means that the highest power that appears in an expression is the power 3.

The term "quadratic" comes from the Latin word "quadratus," which means squared or raised to the power of two. In a quadratic expression, the highest power of the variable is two, resulting in three terms: the quadratic term, the linear term, and the constant term. The term "quad" does not imply there will be exactly four terms in the expression.

How do you work out 3x squared -10x equals -5?
This is a quadratic expression in x. It cannot be solved because it is an expression: there is no equation to solve. Furthermore, the discriminant for the quadratic = (-10)2 - 4*3*(-5) = 100+60 = 160 which is not a square number. There are, therefore no rational factors. While it would be possible to give irrational factors, factorising a quadratic into linear terms containing irrational numbers is rarely useful.
